2 tablespoons homemade taco seasoning (or a 1 oz packet of taco seasoning)
1 tablespoon olive oil


Preheat oven to 425 degrees. Line a 15x10x1″ jelly roll pan with aluminum foil. Place all the vegetables on the foil in a single layer. Drizzle vegetables with olive oil and then sprinkle the taco seasoning on top. Give the vegetables a quick mix until they are evenly coated with the oil and seasoning (I just used my hands- I found that it was easier than anything else I tried). Bake the vegetables uncovered for about 20-25 minutes, stirring once about half way through.

These vegetables make an awesome side dish or even main dish. You can also throw them on a whole wheat tortilla for an awesome meal. You can also mix it into a delicious rice bowl with your favorite toppings, or even as a lettuce wrap.
