- Rest and Slice: Let the steak rest for 5 minutes before slicing it thinly against the grain.
Step 3: Assemble the Tostadas
- Prepare the Base: Spread a layer of warm refried beans over each tostada shell.
- Add the Beef: Top with slices of carne asada.
- Layer the Toppings: Add shredded lettuce, diced tomatoes, red onions, cheese, and avocado slices.
- Finish with a Drizzle: Add a dollop of sour cream and a drizzle of hot sauce or salsa.
