Remove the moisture from the tofu by draining the package and pressing a clean towel or paper towels against the tofu to absorb liquid. Using your fingers pull apart ~1-inch chunks of tofu and place them on the prepared sheet pan.
Add bell peppers, onion, garlic, taco seasoning, and oil. Stir them around until everything is evenly coated, and spread ingredients out in a single layer before placing in the oven for 25 minutes. If you’re using frozen veggies, add 5 more minutes.
