What can I do to make this recipe less boring?

My burrito recipe is really quite boring. I cook 2 lbs of ground beef, strain it. Season it with season salt, black pepper, garlic powder, minced onion, and tapitio. I add refried beans and milk( to let the beans thin up a bit) I put a good amount in a flour torilla with shredded cheese and roll it up. There we go. What can I do to make this recipe less boring but not too spicy(to the point I get heart burn) Thanks!
