They say eggs is a staple in the Atkins diet, and to look for the free-range ones.
For
breakfast, I cook 2 handfuls of spinach and kale with 1 tbsp of olive oil over a pan on med-heat, until the leaves are slightly wilted. Then I add 3 scrambled eggs, and mix together with the spinach/kale... I add my house seasoning, which is garlic powder, salt, and pepper.. then voila, my favourite breakfast, Spinach egg scramble! I sometimes have it for lunch instead of breakfast, too.
For snacks, I cook up some chicken breasts (either baked or bbq'd), and cut them in strips, and have a few when I'm feeling hungry before a meal. That, and a few celery sticks or sliced cucumbers with ranch dip. I buy Babybel cheese for quick snacks, too.
For lunches and dinners, I have a lot of cooked veggies (I don't really like raw veggies, lol) and fish, chicken, beef, pork. There are a lot of veggies you can steam... also, you can stir fry some bell peppers, broccoli, and your favourite meat.
I hope that gives you a few easy ideas
