Preheat the oven to 375°F
Place all the ingredients except for the Frank’s and the brussels sprouts in a large mixing bowl; knead with your hands until all the ingredients are well combined.
Transfer the meat mixture to a loaf pan; press it down and shape the top so it looks nice and round. Cover with as much (or as little) Frank’s as you like (I used about 2 tablespoons)
Place your meatloaf in the oven. Make sure to place a broiler pan or large piece of aluminum foil directly underneath it to collect any drippings that may eventually leak out of the pan.
Bake for a total of 60 minutes then drain excess liquid, set oven to broil and place the meatloaf under the broiler for about 5 minutes or until the top is nice and brown.
Meanwhile, cut brussels sprouts in halves and spread out on a foil-lined baking sheet. Drizzle with olive oil, salt, and pepper.
Remove the meatloaf from the oven and let it rest for at least 20 minutes before serving.
While meatloaf is resting, roast brussels sprouts for 20 minutes.
Drizzle meatloaf with more Frank’s at the moment of serving, if desired. Serve with sprouts on the side.
