Use a mix of mushrooms for the best texture and flavor. Avoid overcrowding the pan to ensure mushrooms brown nicely. Adjust heat level by jalapeño seeds. Fresh lime juice brightens the dish. Warm tortillas before serving. For extra flavor, add soy sauce or smoked paprika. Variations include adding beans, cheese, spice, vegan options, and fresh or creamy toppings. Store leftover filling in airtight container for up to 3 days and tortillas separately.
