1, diced into 1/2-inch cubes red bell pepper
1, diced into 1/2-inch cubes yellow bell pepper
1 cup (frozen or canned, drained) corn kernels
2 tbsp olive oil
1 tsp ground cumin
1/2 tsp smoked paprika
1/4 tsp kosher salt
1/4 tsp black pepper
8 corn tortillas
1 cup, shredded purple cabbage
1/2 cup salsa

Instructions

Step 1: Preheat oven to 425°F.

Frequently asked questions

How long does Rainbow Veggie Fiesta Tacos take to make?

Total time is about 35 minutes (15 min prep + 20 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Rainbow Veggie Fiesta Tacos?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep olive oil from drying out.

Can I substitute ingredients in Rainbow Veggie Fiesta Tacos?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Rainbow Veggie Fiesta Tacos for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.

Is Rainbow Veggie Fiesta Tacos vegetarian?

Yes — this recipe is tagged vegetarian based on its ingredient list. Always cross-check labels for packaged ingredients (sauces, broths, condiments) since formulations vary by brand.
