I gotta say that any sort of tofu based thing is something I'm hoping to really get it into. It's such a great and easy way of getting protein and you can't really make it wrong. For example, while chicken breast is the king of lean meat and getting just that protein per gram efficiency, having to make sure you hit the sweet spot of it not being undercooked but also not too dry, while also ensuring whatever seasoning you do is mixed up and varied enough so you don't get bored of it...Pork chops are also in the category for most of what was mentioned but it's hard to enjoy that to the same degree especially if you mess up the cooking process. Ground beef (and to an extent ground turkey) are probably the straight forward ones while still getting to enjoy the taste factor though that's dependent on the fat contents which I suppose in its own way is a bit of a drawback if you're trying to eat a large portion but also keep it fairly light.
