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

Meanwhile, heat 1 tbsp oil in a large skillet over high; cook burgers with salt/pep 3 min on one side; flip over, cook 2 min, then add 1 slice of cheese to each burger; cover pan + cook 1-2 more min until cooked through + cheese has melted

Toast 2 buns until warm + golden

Assemble each burger with 2 tbsp ketchup + divide between plates with sweet potatoes
