Calphalon Nonstick Pans!!!!!
These are a must have. It is so worth it to have quality cookware. You don't need a lot, just 1 or 2 pans. You may want to go with this one
I personally own the first two, the 10 and 12 inch pan.
So, now that I've established that part, on to the food.
Lean proteins, easy and quick for grilling:
You can get a 4 lb box of individually wrapped tilapia fillets from Walmart for around $12. That's super cheap and they are really good.
Find a local butcher who will fillet a half of a breast, season it and individually vacuum pack it for you.
Lean Ground Sirloin:
Again, get this from a local butcher and have them wrap 1/2 pound packs.
For me, having food available is key. I have my freezer stocked with all of these items and plus some. I also buy the individually wrapped salmon from Sam's club, ground turkey which I have seasoned, separated into 4 oz portions and vacuum packed and frozen. (My brother is a butcher and has an industrial vacuum machine!). He gives me scraps from beef tenderloin, parts that have a tendon in it that he cannot give to his customers as he cuts steaks for local restaurants. Anyway, I take these and season and wrap in individual servings that are easy to defrost and cook. Makes really tasty fajitas.
Frozen vegetables make for easy steaming in the microwave as well.
I love making mexican flavored foods. Grilling chicken or beef with cumin and chili powder seasonings. Or you can buy fajita seasoning mix and just use some of that. You can have 2 white corn toritillas for 90 calories, 2 Tablespoons of sour cream for 40 calories, salsa for 10 calories, sauteed onions and bell peppers for 20 or 30 cal and then your beef or chicken for 150 calories.
The skillets are great for cooking eggs and omelets. I like to eat egg whites and 2 slices of ham in half of a Joseph's Pita
Good luck! I love to cook! The best thing is to start experimenting!
