Dice shallots and sauté in butter over medium heat until translucent. Add red pepper flakes and cook 2–3 minutes.Chop mushrooms - we want them to be the same size as the oats and lentils. To make this process go faster you can use the blender hack: turn your blender on and then drop the mushrooms in while the blade is already running Add mushrooms and sauté until browned (about 5–7 minutes).
Add broth, oats, and lentils. Bring to a boil, then reduce to simmer for ~15-20 minutes until lentils and oats are cooked.
Stir in miso and nutritional yeast. Adjust salt + pepper to taste.
Sprinkle each bowl with everything but the bagel seasoning and top with chives and chili garlic crunch
