Preheat oven to 400°; place 2 large pieces of foil on a sheet pan + oil the foil; divide asparagus onto one side of each foil, then top with a fillet; top each with ½ of butter round + salt/pep; fold empty side of foil over ingredients; working from one end, tightly fold edges of foil creating a sealed half-moon shape; repeat with other foil

Bake 12-15 min until trout is firm, opaque + cooked through

Meanwhile, tear corner of rice to vent + heat in microwave 90 sec (careful—it'll be hot!)

Open foil packs by cutting a slit through center (watch out for steam!) + divide all between plates—delish!
