Make traditional tuna salad new again, with a few simple ingredient switch-ups! Combine McCormick® Mayonesa with Búfalo® Classic Mexican Hot Sauce – a guajillo chile hot sauce – to create a mildly spicy, slightly smoky and refreshingly tangy flavor profile. Scoop tuna salad mixture onto a crunchy tostada shell and top with tomato, avocado, cilantro and red onion.
