Microwave 2 potatoes in their wrappers on high, 6-8 min, flipping halfway through (caution, that's a hot potato!); carefully slice open

Meanwhile, dice ½ of onion; heat 2 tsp oil in skillet over high; add meatballs, break into large chunks + sear undisturbed 2 min; flip meat over, season generously with salt/pep + fave spices, then add onion + break meatballs into small pieces; cook 2-3 min until fully cooked + no pink remains; add 1 cup sauce + warm 1-2 min

Divide ground beef between potatoes + dig in
