As a former employee of taco bell, who checked the ingredient list..... there is nothing spicy in there.
Lemme pull it up.
Ingredients. INGREDIENTS: WATER, TOMATO PUREE (WATER, TOMATO PASTE), VINEGAR, CONTAINS LESS THAN 2% OF SALT, CHILI PEPPER, SPICES, XANTHAN GUM, SODIUM BENZOATE AS A PRESERVATIVE, POTASSIUM CHLORIDE, MALTODEXTRIN, YEAST EXTRACT, DATEM, NATURAL FLAVOR.
Okay, less than 2% of chili pepper.
But I simply can't detect it.
