Tips
Char vegetables aggressively for smoky depth; pale grilled vegetables yield flat salsa. Look for blackened edges.
Don't over-blend salsa verde; leave some texture for body. Pulse in short bursts rather than continuous blending.
Warm tortillas in a dry skillet or over flame just before serving to prevent sogginess from mayo and salsa.
Good to Know
Salsa verde keeps refrigerated in an airtight container for up to 4 days. Avocado mayo best used same day; avocado oxidizes quickly.
Prepare salsa verde up to 1 day ahead. Grill vegetables 4 hours prior; serve at room temperature or gently reheat. Assemble tacos to order.
Serve immediately with lime wedges and extra salsa on the side. Pairs well with cold Mexican lager, agua fresca, or margaritas.
Common Mistakes
Undercooking vegetables to avoid mushy asparagus; grill longer for caramelization
Over-blending salsa to avoid paste-like texture; pulse instead of continuous blend
Over-filling tortillas to avoid taco collapse; use restraint on mayo and salsa

FAQ
Can I make this vegetarian or vegan?
This recipe is already vegetarian. For vegan: substitute mayonnaise with vegan mayo or cashew cream, omit cotija cheese or replace with nutritional yeast.
What if I don't have a grill?
Use a grill pan or cast-iron skillet over medium-high heat. Alternatively, broil vegetables on high for 8-10 minutes, turning halfway. You'll lose some char but gain intensity.
How long do leftovers keep?
Salsa verde lasts 4 days refrigerated. Grilled vegetables keep 3 days. Assemble tacos fresh; leftover assembled tacos become soggy within 1-2 hours.
