Most people overcook chicken, so make sure you're not doing that.
I prefer grilled over anything else. Pound them to similar thickness and toss them on. The plain grill flavor is usually fine for me. Add some spices if you want something different (marinated in soy sauce is one of my favs).
Pan seared in evoo is a quick go to way how I prep the bag o' frozen breasts.
One of my current meals I'm eating a lot of is searing a couple frozen chicken breasts in evoo till done. Take them out and use the oil that is left to pan sear a bunch of frozen veggies and then Salt and pepper to taste. Seems pretty healthy, plus you only end up with 1 dirty pan
