Preheat oven to 425°; chop cauliflower into 1-inch pieces, spread on a sheet pan, drizzle with 1 tbsp oil, salt/pep + ½ seasoning packet; roast 10 min, then flip veggies over + roast 5-10 min more until browned + tender

Meanwhile, microwave beans in a covered, microwave-safe bowl 1 min (or warm in skillet 1-2 min)

Stack 4 tortillas on a plate + wrap with a damp paper towel; microwave 15-30 sec or until warm + soft

Divide cauliflower + beans among tacos, then dollop each with 1 tbsp sour cream—that looks so good!
