Preheat the oven to 425 degrees.
Mix together the lean ground beef, almond flour, egg, worcestershire sauce, onion, garlic powder and salt and pepper to taste in a bowl. Knead with your hands until well combined.
Form the meat mixture into four loaves. Top with the bbq sauce and bake for 20 minutes.
In a bowl, toss the broccoli in the butter and minced garlic.
Remove the sheet pan from the oven and add the broccoli florets.
Bake for another 15-20 minutes until the broccoli is to your liking, and the meat is cooked through.
