Microwave 2 potatoes in their wrappers on high, 6-8 min, flipping over halfway through cook time (caution, that's a hot potato!); carefully scoop out flesh, mash with a fork, season with salt/pep + 1-2 tsp oil

Meanwhile, slice asparagus into ½-inch pieces, discarding any tough pieces; heat 1 tbsp oil in skillet over med-high, add asparagus, salt/pep + sauté 4-6 min until tender + bright green; set aside

Heat lightly oiled skillet over med-high; pat pork tenderloin dry + sear 2-3 min per side until warmed through; cut pork into bite-size pieces

Divide potatoes, asparagus + pork to bowls, then dollop each with 2 tbsp tzatziki
