Stir once.3.Reduce heat to low, cover, and simmer until water is absorbed (15 minutes).4.Remove from heat and let sit covered for 5 minutes, then fluff with a fork.TIPRinsing removes quinoa's natural bitter coating called saponin.

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Select peppers with flat bottoms so they stand upright in the baking dish without tipping over.
- 2For even cooking, choose peppers of similar size so they all finish baking at the same time.
- 3If using dried black beans, soak overnight and simmer until just tender — creamy but not mushy is the goal.
- 4Add a splash of water or broth to the baking dish to create steam; this prevents the peppers from drying out.
- 5Let the baked peppers rest for 5 minutes before serving — the filling sets and the cheese firms up slightly.
- 6Leftover stuffed peppers keep well in the fridge for 3 days; reheat covered in a 350°F oven.
