I really like Chicken Saltimbocca -which almost always contains a combination of chicken, proscuitto, white wine and chicken broth. There are a million recipes out there for it, depending on how complex you’d like to make it.
Chicken Cacciatore is also one of my old-school faves. That’s another one that has some variation, but almost always, it contains some combo of chicken, tomatoes, onions, and peppers.
When I first started cooking, I experimented a lot with a stuffed chicken breast recipe. I’d simply butterfly a chicken breast and then stuff it with a combination of ingredients like, tomato, garlic, basil and mozz or feta, olive, onion, or ham and swiss etc… then fold it together, brush it with egg, dredge it in breadcrumbs and then throw it in a skillet with some olive oil and brown it. I must have tried about a billion different combinations with that one but it was fast, easy and depending on what I stuffed it with, fairly healthy.
