Foods Corn was the most important crop grown, but the Aztecs also grew squash, avocados, beans, sweet potatoes, beans, peppers, and tomatoes. Each farmer gave the Great Speaker a little of his crops. The Aztecs ate a lot of different vegetables, but not that much meat. There were a few big animals that were hunted, but the Aztecs didn't keep cattle or sheep. They didn't need meat in their diet, though, because the vegetables they ate, such as corn and beans, were full of protein. A sort of corn pancake, called a tlaxcalli, was eaten with most meals.
