How Chipotle Sanitized the Mission-Style Burrito for America | Eater
"A Mission District taquería credited with producing the first documented Mission burrito in 1962, where a cook fused two flour tortillas edge-to-edge to create an oversized, foil-wrapped portable meal. That early innovation sparked demand for larger custom tortillas and helped define the Mission-style formula: open-line kitchens, trays of meats and toppings for customer assembly, quick grilling or pressing, and the signature foil swaddle." - Gustavo Arellano
