Mushroom and Vegetable Tacos

These mushroom and vegetable tacos are a quick weeknight meal, ready in about 45 minutes. The filling comes together in a single pan, with tender mushrooms, zucchini, and carrots seasoned with taco spice. Serve them in warm taco shells with crisp lettuce and a dollop of guacamole. To speed things up, you can use pre-sliced mushrooms and grate the carrot and zucchini in a food processor.
