I really enjoy these tacos. Normally, I would add green pepper to saute along with the onion and garlic when I make beans but I didn't have any green pepper in the house. The last one was used for peppers and eggs. However, I did have a zucchini in the fridge. I sliced it and quartered it and added it as a topping along with the salsa and cheese and cilantro. It added a nice crunch, I'd do it again that way.
