Random and STRONG food cravings!?

Usually I am a healthy,nutritious and careful eater. I try to eat foods that are good for me and I only go crazy with carbs every now and then. But recently, I've been having the strongest food cravings of my life. I need to meat, lots of it. And cheese popcorn. I just wake up and have the strongest craving for something random, and a lot of it. Today I ate a lean cuisine,hot pocket and some sausage for lunch, just because it had meat in it. I need to get back to my healthier self. Or else I will gain tons of weight. Any other alternatives to something nice and tasty to munch on that is also nutritious? Just until I can wean myself off of this meat and popcorn craving.
