Fajitas-
cut meat (chicken or beef) into strips
cut equal amounts bell pepper and onion into strips (about 2x as much veggies as meat)
sauté with garlic, chili powder, a small amount of soy sauce (or terriaki)
in a separate pan cook the peppers and onions on low heat with a little bit of olive oil, cumin (don't use too much, about two shakes per person you're cooking for), garlic and soy sauce (coriander and ground ginger optional). Save about 1/3 of the vegetables
when the veggies are just starting to get soft combine the meat and veggies and throw in the unused vegetables
let the water cook off and make sure your meat is cooked all the way.
in a pan, melt cheese (Monterey pepper jack is best) onto a tortilla.
wrap the tortilla and veggies up together with some salsa and avocado.
one pepper and one onion will make three monster burritos.
For a sandwich-
bake a chicken breast with rosemary, italian seasoning (dried parsley, basil and oregano) garlic and olive oil.
cut into slices and voila (that's french, or freedom if you prefer) for there it is. A lunchmeat that cost $.99-2.99 depending on whether there was a sale or not, instead of crappy pre-processed $4.00-7.00 stuff.
a couple of shakers of seasonings will change everything, and it won't take long to figure out what works well together
-garlic (fresh cloves are the best, followed by peeled cloves, in jar minced, and finally powdered)
black pepper (a grinder is a good investment IMO)
basil (fresh is way more flavorful, but much more expensive and a pain in the butt sometimes)
ginger (root or ground)
cumin
chili powder
italian seasoning
