Here are a couple suggestions you can look into (assuming you are looking for protein dishes):
Amaranth and quinoa are non-gluten grains that are very high in protein.. and brown or wild rice are not too bad either .. you could add lots of veggies to a dish with those grains to make a meal. Most veggies have some protein: apparently 1/2 cup of cooked spinach has 7 grams of protein... if you like spinach you can add it to lots of different meals. A serving of corn or potatoes has 4 grams of protein. Nuts (plain or raw nuts have no gluten) are high in protein and you can add them to veggie or grain dishes.
