Mix together the beef, chopped onion, BBQ seasoning, salt, pepper, egg, milk, and bread crumbs in a large bowl. Using your hands works best!
In a separate bowl, combine the soy sauce, Worcestershire sauce, ketchup, brown sugar, and Picante sauce.
Mix in half of the sauce with the meat mixture, reserving the rest of the sauce. Combine well, but do not over-mix.
Grease the cups of your muffin tin with a little olive oil or spray lightly with cooking spray. Distribute the meatloaf mixture evenly among the muffin cups, and then spoon the reserved sauce over each muffin. (You may have a little sauce leftover…)
Bake in a 400°F oven for 25-30 minutes, until the meat is cooked through.
Notes
I get 12 meatloaf muffins. The meat doesn’t come up past the top of the “cup”. The sauce will bubble a little while the meatloaves are baking, so if you fill them higher, it might get messy in there. If you happen to have a little more meat than 1 1/4 pounds., just use a second muffin tin for the extra ones.
