In a large microwave-safe bowl, mix together the tortilla chips, popcorn and corn cereal.
In a small pot, melt the butter over low heat. Stir in the tequila, hot sauce, salt and lime zest and juice until well combined. While mixing, slowly pour over the cereal mixture; mix until everything is well coated.
Microwave for 5 to 6 minutes, stirring every 2 minutes. Transfer to a baking sheet lined with parchment paper and let cool. Store in a resealable bag or airtight container.
