Hi and welcome to DC! I've got some ideas for you!!
Whey protein is good in shakes but not something I would consume frequently. Certainly not in place of fruits & veggies. Nut butters are excellent, I eat a tablespoon with a banana or apple. Nuts & seeds with dried fruit are great for snacks.
Make some hummus (super easy and not expensive), boil a dozen eggs like jkath suggested, remove the yolk and put a spoonful of hummus in it's place. Excellent low carb, high protein snack. Hummus is also excellent for dipping veggies in!
For a main meal, Turkey Chili is so tasty and easy. Buy a package of lean ground turkey, onions, mushrooms, green bell peppers, can of kidney beans, 2-3 cans crushed tomatoes, chili powder & oregano. Cook the veg in some olive oil, add the meat & spices and cook till brown. Add tomatoes & beans and simmer for 30 minutes.
Breakfast can be scrambled egg whites with some low fat cheese and lean bacon. Steel cut oatmeal should be a staple breakfast for you, cook in water, add cinnamon & nutmeg and chopped fruit (I add blueberries or dried figs or prunes). Plain low-fat yogurt with 1 cup of berries is another good breafast.
Lunches can be a big mixed green salad with turkey & ham and low fat cheese. Grilled chicken salad with chopped veggies (mushrooms, onions, tomatoes).
This is an excellent Turkey Meatloaf recipe I used to make all the time, served with a nice big green salad. Turkey Meatloaf Recipe at Epicurious.com
Chicken stir-frys with red & green bell peppers, onions, broccoli and mushrooms. And don't be afraid to try tofu as well!!!
Hope this gives you some ideas, all good low-carb high protein food.
