I wouldn't be quick to dismiss protein powders... they seem expensive but if you do the math on a serving of meat and how much meat you have to eat a day, the price for powders (even ordered online) is not much worse and in some cases better than meat! I mean, I can eat a package of chicken in 2 meals and that costs me an average of $7.00 for the package. The most expensive protein powders I know of might be $3-4 dollars a serving. So, it averages about the same. There are exceptions as some meats are cheaper, but the point I'm making is that powders seem expensive up front but last typically 20-30 days!
Two favorites but they are expensive so I'm not going to include these:
AST-SS Muscle XGF - 7 different proteins, 18 g fat, 7 net carbs... good stuff! Expensive
AST-SS VP2 - Fast acting super great protein, 2 carbs, no fat, great preworkout... mixes with a spoon

Expensive

My official sources:
American Whey - Probably the most economical 100% whey isolate ion filtered, blah blah, you can order from dpsnutrition.com a 10 pound bucket for $59 which is pretty darn good for the quality. It has 6 grams carbs per 20 grams protein, so it can crunch your carb numbers pretty quick
C.Worthy & Co. Atlantic Salmon - Wild Caught Sold at Sams club for $20 (3 lbs!!) - This is (in my opinion) the perfect meat. One fillet is 12g fat, 0 carb and 41g protein. Heats to perfection in the micro. Mix some sour cream mixed with green onions (chopped) and you have a perfect dip.
All Whites (Better N Eggs Company) - This is pasteurized 100% egg whites which means 100% bioavailable. You can drink it raw! Because of this, you can get big time protein. 8 ounces (24g protein) plus a TBSP safflower oil (14 grams fat) plus a scoop of american whey (20 protein, 6 carb) gives you 44g protein, 6 carb, and 14.5g clean mono and poly fats. This is a wonderful low carb meal replacement. Throw in some fish oil tabs for more fat. Safflower oil (to me) is the hidden gem. It's filled with mono fats and blends really well with liquids with no added weird flavor that you get from say olive oil.
Shelled Walnuts - Diamond - 20g fat (mostly poly), 2 carbs, 5 protein, blended or in combination with a all whites is a bang.
Chicken Breast - Cold, cubed and in a salad. I COMPLETELY HATE reheated chicken breast. It smells weird to me. I don't mind freshly grilled but reheated is disgusting. For some reason cold is fine.
Flank Steak - I'm not a huge red meat eater (mostly because the price but also because sams club / walmart red meat is loaded with steroids/antibiotics and I honestly think the corn they feed these animals affects the meat and my body... I swear it makes me fatter.) Anyway, the taste of flank steak to me is unbelievable. Another one of those meats I don't prefer reheated, but off the grill it doesn't even reach my plate. If I eat flank steak all day for every meal, my ketones show up. It's pretty awesome.
