Preheat the oven to 350 F.

Place the chicken in a medium bowl or large resealable bag and pour the Greek dressing over the top. Marinate the chicken on the countertop for 20 minutes. (Any longer and the lemon juice will start to break down, or “cook,” the chicken.)

In a medium bowl, combine the bell pepper, tomatoes, capers, parsley, salt, black pepper and feta.

In a 12-inch cast-iron or other oven-safe skillet, melt the butter with the olive oil over medium-high heat. Remove the chicken from the marinade and let any excess marinade drip back into the bag. Place the chicken top-side down in the skillet and sear for 4 to 6 minutes. Turn the chicken over and divide the pepper and feta mixture over the top.

Slide the skillet into the oven. Bake for 15 to 18 minutes, or until the chicken is cooked through. Carefully transfer the chicken to a platter and let it rest for 5 to 6 minutes before serving.

For Grandma’s Greek Dressing: Pass the garlic through a garlic press into a glass jar or resealable storage container. Add the oregano, salt and pepper. Pour in the lemon juice and olive oil. Shake. Pour. Swoon. Store the salad dressing in the refrigerator, but pull it out 10 to 15 minutes prior to using to warm up the solidified oil, or run the jar under warm tap water. Store in the refrigerator for 3 to 4 months.

For Charred Peppers: Grill: Heat a grill to medium-high. Place a pepper (or peppers) on the grates, close the lid and let it char for 5 minutes. Rotate and repeat this process until all sides are charred. After 12 to 15 minutes, the skin should be black and blistered. Gas stovetop: Using metal tongs, hold the pepper over a medium-high flame, rotating it to create an even char. Oven: Preheat the broiler to high and crack the oven door. Place a washed pepper on a foil-lined, rimmed baking sheet and slide it under the broiler, rotating it every few minutes until it is charred.
