Chicken breasts, lean beef, pork, beef jerky, fish - canned tuna, fresh, shellfish like shrimp, clams, crab, lunchmeat, tofu, tempeh (sp?), dairy products like cottage cheese, yogurt, cheese, milk, high-protein grains like quinoa, lentils, oatmeal, nuts, eggs, egg whites, vegetarian products like frozen veggie burgers, high protein cereals like Kashi GoLean, protein bars (bought or homemade), protein powders made into shakes or baked into baked goods. I love protein!
You didn't mention whether you have any eating restrictions. If you don't eat a lot of meat, I mentioned a few meatless options, and I'm sure the vegetarian and vegan sub-forums have some ideas too.
Protein shakes. GNC sells protein powder (100% whey protein powder, vanilla, plain, choc). You can make a shake out of a scoop of powder (120 cals/20g of protein), yogurt or skim milk, some frozen fruit, maybe a tspn of pbutter. Very yummy and sticks w/you. I personally find that the protein powder makes me thirsty so I end up drinking lots of water.
Oh! Also, if I want a low-cal dessert, I throw a cup of skim milk, some protein powder, and two tablespoons of fat-free sugar-free pudding mix in the blender. Pour into two dishes, refrigerate for awhile, and you have a great protein-fortified dessert.
i usually have chicken dipped in sour cream or mayo... i add things to my normal foods, like adding cheese to salads, adding a handful of nuts in somewhere or seeds helps
add lentils to soups, add stuff in to your regular foods its easy
