Get your oven going at 220°C. Put a frying pan on medium heat, toss in the ground beef, and cook it until brown. Scoop off any grease. Throw in the chopped bacon, onions, ketchup, mayo, and mustard. Sprinkle in the salt and pepper. Mix it all up well, then set aside.

Grab a spoon or a little knife and carve out a hole in each frozen tater tot to make a small cup. Spoon the beef mix into each one. Top every tot with some cheddar shreds.
03 -
Spread the filled tater tots on a baking sheet with parchment underneath. Pop them in the oven for about 15–20 minutes. You want the outsides crisp and the cheddar all melty.
04 -
Stir the mozzarella and any leftover beef mix together in a bowl. When the tater tots come out of the oven, mound some of this cheesy filling right on each one.

Slide them back into the oven and bake 5–10 more minutes till the cheese gets gold and bubbly. Dig in while they're hot and oozy.
