Perfect for beginners, this easy sheet pan dinner-style sandwich brings together crispy panko chicken, a smoky romesco sauce, and a refreshing salad mix—all nestled inside golden, cheesy focaccia. It’s fast, customizable, and ideal for picnics, meal prep, or a relaxed weeknight bite.

Why This Recipe is Special

What sets this sandwich apart is its thoughtful layering of textures and flavors. The crispy chicken adds crunch, while the creamy, zesty salad and velvety romesco sauce bring brightness and balance. The dish doesn’t require fancy equipment or advanced techniques—just a few simple steps that anyone can master. Even better, every component can be prepped ahead of time, making it an ideal option for those easing into the rhythm of home cooking.

Ingredients and Preparation

Chicken Breast: Provides lean protein and becomes wonderfully crisp when coated with panko breadcrumbs. If you’re vegetarian, tofu makes a great substitute.

Flour and Egg: These help the panko breadcrumbs stick to the chicken. Olive oil can replace the egg in vegan versions.

Panko Breadcrumbs: These Japanese-style breadcrumbs create a lighter, crispier coating than regular breadcrumbs.

Romesco Sauce Ingredients:

Jarred Roasted Red Peppers: Bring sweetness and depth.
Sun-Dried Tomatoes: Add umami and richness.

Garlic and Almonds: Lend earthiness and a nutty crunch.
Olive Oil and Balsamic Vinegar: Smooth out the texture and add acidity.
Paprika and Salt: Enhance flavor with a smoky kick.

If you don’t have almonds, any nut will work—walnuts or cashews are great alternatives.

Salad Components:

Sour Cream and Mayonnaise: Offer creaminess and body to the salad dressing.

Lemon Juice and Black Pepper: Add tang and heat.
Grated Parmesan: Delivers salty, savory flavor.
Lettuce and Rocket (Arugula): Bring freshness and crunch.

Focaccia Bread: A fluffy yet sturdy base for all the fillings. Any soft sandwich bread or ciabatta can be swapped in.

Garlic Parsley Butter: Infuses the bread with savory herb flavor. For dairy-free options, plant-based butter works perfectly.

Step-by-Step Instructions

Step 1
Slice the chicken breasts in half horizontally to make thin cutlets. Dredge each cutlet in flour, then dip into a whisked egg, and finally coat with panko breadcrumbs. Pan-fry over medium heat with a bit of olive oil for about 4 minutes per side until golden and crispy.

Step 2
In a blender, combine the red peppers, sun-dried tomatoes, garlic, almonds, olive oil, balsamic vinegar, paprika, and salt. Blend until smooth. If it’s too thick or doesn’t blend easily, add a little more olive oil.

Step 3
Once the chicken is crispy and cooked through (it should feel firm to the touch and have no pink inside), remove it from the pan and place on paper towels to absorb extra oil.

Step 4
In a bowl, mix sour cream, mayonnaise, lemon juice, parmesan, and black pepper. Fold in the finely chopped lettuce and rocket until everything is evenly coated.

Step 5
Preheat the grill. Mix softened butter with minced garlic and chopped parsley. Slice the focaccia in half and spread the butter mixture evenly on both inner sides. Grate parmesan over the butter. Grill for a few minutes until the bread is golden and bubbling.

Step 6
Assemble the sandwich: Spread romesco sauce on both sides of the grilled focaccia. On the bottom half, layer the crispy chicken and salad. Top with the other slice of bread.

Step 7
Wrap the sandwich in parchment paper if taking on the go, or enjoy immediately while still warm.

Beginner Tips and Notes

If the chicken browns too quickly, reduce the heat—this helps cook it through without burning the coating. For extra-crispy breading, lightly press the panko into the cutlets. Don’t overfill the sandwich; layering strategically prevents it from falling apart. A food processor or small blender makes the romesco sauce effortless, but a hand blender works too.

If you’re short on tools, you can toast the bread in a pan instead of using a grill. Use pre-grated parmesan to save time, and chop all ingredients beforehand for smoother assembly.

Serving Suggestions

This sandwich pairs beautifully with:

A side of sweet potato fries or roasted vegetables
A chilled cucumber or fennel salad
A light sparkling lemonade or iced tea

For leftovers, wrap tightly in parchment or foil and refrigerate for up to two days. To reheat, toast lightly in a pan or oven for a crisp refresh.

Romesco is a Spanish-style sauce made from roasted red peppers, nuts, garlic, and olive oil. If needed, you can use red pepper hummus or a roasted tomato spread as an alternative.
