What are good sources of protein for vegetarians?

Vegetarian sources of proteins -- that are also carbs -- include beans (soybeans/edamame are a complete protein), quinoa (a grain you can prepare like rice or like oatmeal or make it with some cheese and broccoli heads; note: quinoa pasta will provide a little less protein). Vegetarian sources of protein that are also healthy fats include nuts and seeds. One seed in particular, hempseeds, provide a complete protein. So instead of a banana, add a nut butter (you can even freeze this and make it a great dessert), instead of just ice cream, have a 1/2 scoop less and add berries and hemp seeds.
