Engage the 'Sauté' function on your multi-functional pressure cooker (such as Instant Pot). Introduce the bacon, oregano, and garlic, allowing them to dance together until the bacon achieves a delightful crispness, approximately 5 minutes. Then, welcome the Brussels sprouts, onions, mushrooms, beets, butternut squash, bell pepper, paprika, chili powder, salt, and pepper into the aromatic embrace. Stir until vegetables begin to soften, 5 to 10 minutes. A good way to test is piercing the beets with a fork.
