I heat olive oil in a saucepan or on the Instant Pot’s sauté mode, stir in tomato sauce, chili powder, cumin, onion powder, garlic powder, and smoked paprika. After adding broth, I simmer for 5–10 minutes until slightly thick, then season with salt and pepper.
While the sauce cooks, I scramble the eggs until just set—soft and moist. In the same pan I sauté bell peppers and onions until soft, add chicken and beans if using, season with cumin and chili powder, then fold in shredded cheese.
I warm tortillas briefly to prevent cracks, fill each with a scoop of filling, and roll them up. Placing them seam-side down in the Instant Pot insert, I pour sauce over the top and sprinkle the rest of the cheese.
I seal the lid, set to high pressure for 5 minutes, and quickly release it. For a golden top, I pop the insert (or transfer to a baking dish) under the broiler for 5–7 minutes until bubbly. Rest a few minutes before serving.
