Looking for a fresh twist on taco night? These Grilled Vegetable Tacos with Guacamole are my go-to recipe when I want something that’s both healthy and bursting with flavor. The combination of char-grilled vegetables and creamy homemade guacamole creates an incredibly satisfying meal that even dedicated meat-lovers will enjoy. What I love most about this recipe is how customizable it is – you can use whatever seasonal vegetables you have on hand.
Ingredients
For the Grilled Vegetables:
- 2 zucchini, sliced lengthwise
- 2 bell peppers (any color), quartered
- 1 red onion, cut into thick rings
- 2 portobello mushrooms, stemmed
- 2 tablespoons olive oil
- 1 tablespoon chili powder
- 1 teaspoon ground cumin

Recipe Notes
- If you don’t have a grill, you can use a grill pan or roast the vegetables in the oven at 425°F for similar results.
- Make sure your avocados are ripe but not overly soft for the best guacamole texture.
- To prevent the guacamole from browning, press plastic wrap directly onto its surface if not serving immediately.
- Double the guacamole recipe if you like generous portions – it keeps well in the refrigerator for up to 2 days.
- For extra flavor, try marinating the vegetables for 30 minutes before grilling.
- To keep tortillas warm during serving, wrap them in foil after heating.
