Preheat the oven according to the package directions for the pizza crust.
Cook the ground beef, breaking up the meat, until it's cooked through. Drain any excess grease. Cook the bacon until crispy, flipping as needed. Transfer the bacon to a paper towel-lined plate to drain. Once cool, crumble it into pieces.
Spread shredded cheese evenly over the pizza crust. Then top the cheese with the ground beef and bacon.
Cook the pizza according to the package directions for the crust. Remove the pizza from the oven.
While still hot, top with tomatoes, lettuce, and red onion. Finish with a zig-zag or swirl of mayonnaise over the top of the pizza. To make adding the mayo easy, put it in a food storage bag and snip the corner, resulting in a makeshift piping bag. Cut into 6 slices and enjoy!
Notes
You can use a premade pizza crust, buy pre-made pizza dough, or make homemade pizza dough. Use the package or recipe for guidelines regarding oven temperature and cooking time.
