Bring a pot of water to boil and salt generously.
In a large skillet, sear beef on high heat on both sides. Crumble and cook through, then add salt, pepper, onion powder, and garlic.
When garlic is fragrant, add carrots and tomatoes. Cook until tomatoes begin to wrinkle, at which point they can easily be burst with a wooden spoon.
Add soy sauce and deglaze pan.
Reduce heat and add zucchini. When zucchini is partly cooked but still toothsome, add teriyaki sauce, banana peppers, and crushed red pepper flakes.
Put the tortellini in the boiling water, then wilt the spinach into the hot sauce. When the tortellini is ready, put in with the sauce and vegetables and stir to combine.
