Prepare the cauliflower. If using fresh cauliflower, dice in food processor until it reaches the appearance of rice. Be careful not to over-chop. If using frozen cauliflower rice, thaw using directions on package. Set aside.

Put oil in skillet on medium heat. Add onion, jalapeño pepper, and garlic and sauté until translucent.

Turn skillet to medium-high heat and add the cauliflower, Rotel, mixed vegetables, Roma tomato, salt, chili powder, and chili pepper. Stir everything together and let cook for 5 minutes (stirring at least once a minute to make sure nothing sticks to the pan).
