Erica’s Thoughts
Who’s up for a gigantic sandwich?? 🙋🏻♀️
Do y’all know what I don’t like doing? Making a bunch of sandwiches for a bunch of people. ‘Batch-making sandwiches’, if you will. This is obviously a necessary thing that happens often in my world – like when my family is over, and I want to feed them lunch before a show or performance, or when we’re going to the park or beach and need to pack a picnic. I always think it’s going to be quick and easy but tell me why it takes five-ever to make sandwiches for that many people.
Enter our solution: One gloriously huge chicken sandwich on pillowy bread with melty cheese, lots of pesto mayo and fresh veggies. A couple of keys here: 1) make sure you grab a loaf of focaccia or ‘flatbread’ that is thick enough to slice in half lengthwise, 2) opt for great-quality, thinly-sliced deli chicken or I often make this with leftover balsamic grilled chicken breasts (so good) and 3) don’t skimp on the sauce, my loves. Sun-dried tomato pesto + good-quality mayo = magic.
If you love a good deli-style sandwich or panini, this one is for you.
First, gather everything you need:

- Bread: ideally, a focaccia loaf. I love the ones from Trader Joe’s! They have one with sun-dried tomatoes and one with caramelized onions. You can find a loaf similar to these in the bakery section of most major grocery stores.
- Condiments: any type of pesto + good quality mayo. I like sun-dried tomato pesto which you can find in the pasta/tomato aisle of most grocery stores. You could also make your own basil pesto.
- Protein: I prefer chicken, but deli turkey works here too.
- Veggies: red onion, tomato, and arugula or microgreens.
- Cheese: I use a combo of Gruyere and fresh mozzarella cheese. Monterey Jack or mild Swiss cheese also works.
- Seasonings: every good sandwich needs seasoning! It’s pretty simple here – sea salt, black pepper and your favorite all-purpose seasoning. Feel free to add a pinch of red pepper flakes for heat, lemon juice for a little zing or balsamic glaze for extra richness.
How to Make a Really Good Chicken Focaccia Sandwich:
Preheat oven to 400°F. Line a sheet pan with parchment or a silicone mat.


Slice the focaccia bread horizontally with a serrated knife, so you have a top and a bottom. Work carefully, and make sure the loaf is sitting flat on the cutting board, don’t try to hold it up while you slice. Drizzle cut sides with olive oil. Toast face up for 5 to 7 minutes until lightly crisp and golden brown.


Mix pesto and mayo until smooth. Spread on both halves.


Sprinkle cheese on both halves. Layer chicken on the bottom half. Add red onion.


Return both halves to oven until cheese melts and the chicken and onions are warmed through, about 8 minutes.
Pat tomato slices dry with a paper towel. Layer tomatoes over onions. Season with salt, pepper, and all-purpose seasoning.


Add microgreens or arugula and a light drizzle of olive oil and pinch of salt.


Place the cheesy top half of focaccia onto the sandwich. Press gently, slice, and serve warm. WOW. It’s a good day today.


FAQs
Regular basil pesto works too! Even better if it’s homemade pesto 😉
It is still good cold, but I prefer it warm with the melty, gooey cheese. To reheat, I pop a piece of the sandwich in my air fryer at 350 degrees for about 5 minutes.
Any soft, large, thick and flat loaf of bread. I love how soft and pillowy focaccia is; this sandwich won’t turn out as well on hard/chewy loaves like a baguette.
Wrap tightly in plastic wrap or store in an airtight container and refrigerate for up to three days.
