Ingredients Notes
Simply made with chicken breasts, seasonings, and fennel, this recipe is easy to throw together and toss in a large storage bag to marinade for 30 minutes and then throw it in the oven for a quick 30 minutes.
- Chicken Breasts: we cut two large boneless skinless chicken breasts lengthwise and then pound them flat with a mallet. Making them thin to cut down on cooking time. Alternatively, you can use chicken thighs in this recipe.
- Pepper Sauce: I used a store-bought Calabrian pepper sauce but you can also use a tomato sauce and add chili pepper flakes if you want it a little spicy.
- Fennel: I only needed one large fennel bulb, but since I could only find small ones, I used two instead.
- Italian Seasoning: Usually found in the spice aisle and made with a mix of dried basil, oregano, rosemary, thyme and sometimes garlic powder.
- Extra Virgin Olive Oil, Red Onion, Cherry Tomatoes, Salt, Black Pepper, Garlic Powder.
