Ingredients

Directions

Prepare the vegetables

  1. Heat the outdoor grill.

  2. In a bowl, stir together lime juice, ground cumin, chili powder, salt, and cayenne pepper.

  3. Place the onion rings on a plate and brush both sides with some of the lime juice mixture. Microwave the onion rings on high for 1 minute. Set the onion rings aside.

  4. Place the asparagus spears in a plastic bag, the bell peppers in a second bag, and the yellow squash and zucchini in a third bag. Divide the remaining lime juice mixture among the three bags. Coat all vegetables with nonstick spray.

Grill the vegetables

  1. Grill the asparagus for 10 minutes. Grill the onion rings for 8 minutes.

  2. In a grill basket, cook a single layer of bell peppers for 10 minutes. Remove the bell peppers from the grill.

  3. Add the yellow squash and zucchini in a single layer to the grill basket. Grill the squash and zucchini for 6 minutes.

  4. Place all cooked vegetables on a platter.

Assemble and serve

  1. Heat the tortillas according to package directions.

  2. Spread each tortilla with 2 tablespoons of refried beans. Top each tortilla with ¾ cup of cooked vegetables. Sprinkle 1 tablespoon of shredded Mexican cheese blend on each tortilla. Fold each tortilla in half.

  3. Repeat steps 17–20 with the remaining tortillas and filling.

  4. Serve the fajitas with guacamole and salsa.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lime juice
Adds acidity and bright flavor that seasons the vegetables before grilling.
Refried beans
Adds moisture and creamy body that holds the filling inside the tortilla.
Flour tortillas
Provide the soft wrapper that holds the grilled vegetables together.
Bell peppers
Add sweetness and char from grilling, giving the filling its main flavor.
Asparagus
Adds tender texture and a grassy flavor that browns slightly on the grill.
Mexican cheese blend
Melts into the warm filling, adding fat and savory richness.

The step that matters

Grilling the vegetables in batches by type. Vegetables with different densities cook at different rates, so grilling each type for its own time keeps them tender-crisp rather than mushy or burnt.

Flavor stand-ins for the onion

How well each one fits the dish's main ingredients (lime, cumin, pepper, asparagus, flour, beans, cheese):

  3. Carrotbetter flavor fit
  4. Onionthe original

Fit is the average pairing score against lime, cumin, pepper, asparagus, flour, beans, cheese. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
