For the tenderest, juiciest chicken I've ever had: Pound chicken breast to between 1/4 inch, set aside.
In a 10-inch skillet, melt 2 tbsp butter and sautee' 1 small onion (cut in half, then sliced thinly, so you almost have shreds of onion) and 1 clove garlic, minced, until soft. add 1/4c dry white wine (can be omitted) and enough chicken stock to bring contents to about 1/4 inch. Add 1-4 tbsp lemon juice (depending on your personal tastes) and enough sugar to balance the lemon without making it actually sweet-tasting. Start with a large pinch, stir it in, then add more if needed. If necessary, add a touch of extra salt. If you're using regular chicken stock, not low sodium, you may not need salt. Bring liquid to a very low simmer.
While liquid heats, dredge chicken in cornstarch, then egg, then more cornstarch. When liquid reaches low simmer, add chicken. cook until top edges turn white, adding more liquid (water or wine) if necessary. Turn chicken. I find it difficult to take a temperature when the chicken is this thin. If you do too, just check with a fork to see when it's opaque and white all the way through. This chicken cooks fairly quickly, so don't walk away. It's important to cook this over a fairly low heat once the chicken is added so the liquid never reaches a full boil.
Serve over pasta or rice with cooked broccoli or spinach (or your other favorite vegetable).
I also love pounding it thin, dredging it in seasoned, salted flour and pan-frying in a thin layer of oil, olive or veg, depending on seasonings. 2 of my favorite seasoning combinations are: Basil and oregano, cooked in olive oil with fresh sauteed garlic
Chile powder, onion powder, and a touch of cinnamon, cooked in veg oil
I also love chicken breast cut into 1/2x2 inch pieces, marinated in lime juice, salt, and cilantro, and sauteed. sautee corn (fresh cut from the cob is best in this) with lime and more cilantro. Serve in multi-grain tortillas (or white, if you must
) with sour cream or plain yogurt and sharp white cheddar.
I'm a fan of chicken, if you couldn't tell. :)
