In a medium bowl, toss the shrimp with olive oil, smoked paprika, cumin, garlic powder, salt, and pepper.

Heat a skillet over medium-high heat and cook the shrimp for 2-3 minutes per side, or until they turn pink and opaque. Remove from heat and set aside.
In a separate bowl, mash the 3 avocados with lime juice. Adjust seasoning to taste.

1 small jalapeño, seeded and minced, ¼ cup sour cream, ¼ cup fresh cilantro, chopped
Garnish with extra cilantro and serve with lime wedges on the side.
Lime wedges, for serving
Notes
To save time, use pre-cooked shrimp and warm them briefly in the skillet with the seasoning.
Instead of mashing avocados, use store-bought guacamole for a quick shortcut.
Place them in a 350 degrees F oven for a few minutes to keep them crispy before serving.
For a cleaner drizzle, put sour cream in a small plastic bag, cut a tiny hole, and squeeze over the tostadas.
If desired, you can substitute grilled chicken, tofu, or black beans instead of shrimp.
Add a dash of hot sauce, chipotle mayo, or extra jalapeños for more of a kick.
Sprinkle cotija or queso fresco on top for extra flavor.
Add shredded lettuce or thinly sliced radishes for extra texture.
The filling is also delicious served on soft corn or flour tortillas instead of tostadas
Additional Serving Suggestions:
Serve with Mexican street corn, black beans, cilantro-lime rice, or a side salad.
Set up a tostada bar and let everyone assemble their own tostadas with additional toppings like cheese, pickled onions, or extra salsa.
How To Handle Leftovers:
The best way to store leftovers is to keep all the components separate, so only assemble the tostadas that will be eaten.
Store cooked shrimp in an airtight container in the fridge for up to 2 days. Reheat gently in a skillet over low heat for best texture.
Store the avocado mash in an airtight container with plastic wrap pressed against the surface to minimize browning; use within 24 hours.
Keep the tostada shells in an airtight container at room temperature to stay crispy.
