I buy boneless/skinless chicken breasts and use them for all sorts of meals. Veggies that have protein in them are usually low-fat

2.3g protein, 22 calories, and .3g fat in half a cup of broccoli. I also substitute ground turkey for any kind of beef thing I would make(7% fat usu.). I'm lactose intolerant so cheese/milk/yogurt are all not options for me, I round out my daily protein intake with a 90 calorie, 0 fat, 23gprotein shake in the morning and sometimes Instone pudding(20g protein, 100 calories, I think 1-2g fat) in the evenings if I want something sweet but need to bolster my daily protein count. Lean steak is good too if you can afford it, or deli meats of decent quality.
