Crispy tostadas with various toppings served at posada parties are a festive snack. This protein-rich, family-friendly dish is a fresh, easy option for holiday gathering appetizers.
Preheat the oven to 350°F and arrange tostada shells on a baking sheet. Warm them for 3–5 minutes to enhance crispiness.
Heat refried beans in a small saucepan over low heat, stirring occasionally, until just warm and creamy. Do not let them dry out.
In a separate bowl, mix shredded rotisserie chicken with salt, black pepper, and a tablespoon of hot sauce for extra flavor.
Spread a generous layer of warm refried beans on each tostada shell, then layer with seasoned chicken.
Top with romaine lettuce, diced tomatoes, and cotija cheese. Finish each tostada with a drizzle of sour cream and extra hot sauce, and serve with lime wedges.
