Preheat oven to 425°; rinse + drain garbanzo beans

Place 2 large pieces of foil on a sheet pan + oil the foil; divide + layer cauliflower + beans to the center of each, then drizzle on pouch of sauce

Bring the long edges of foil together + roll to seal, leaving 1-inch of space above ingredients; repeat with side ends of foil— your pack is sealed!

Bake 22-25 min until cauliflower is tender (watch out for steam when opening!), add 1-2 tbsp sour cream to each + top with thinly sliced onion
