In a small sauce pan, bring the water to a boil. Add the dried TVP, turn off the burner, cover the pan, and allow the TVP to soak up the water for about 10 minutes.
Meanwhile, in a large sauce pan, heat the olive oil on low heat. Add the red onion and garlic and sauté for about 5 minutes until the veggies begin to soften. Add the tomatoes with their juice and continue to cook on low for 5 more minutes.
Add the TVP mixture and the taco seasoning to the onions, garlic, and tomato, and stir to combine.
Taste to season - depending on the taco spice you use you may want more heat, salt, or cumin.
Serve the TVP Taco Mix in warmed corn tortillas, adding plenty of fresh toppings such as tomatoes, radishes, cilantro, red onion, or guac.
