400 g fresh shrimp, unpeeled, with heads (250-300 g if heads removed)
2-3 Roma tomatoes
1-2 cucumbers
1/2 large red onion
1 large mango
2 avocados
5-8 limes
2 tbsp smoky hot sauce (or your favorite or available chili pepper)
salt
3 tbsp olive oil
tostadas for serving
Instructions
Slice onions into strips, place into a large bowl, cover with salt and lime juice and mix.
While onions are marinating, peel the shrimps and cut into bite size pieces. Add to the onions.
Cut the fish into bite sized pieces, add to the onions. Mix the contents of the bowl thoroughly and make sure everything is covered with lime juice. Add more lime juice if necessary.
Cut cucumbers, tomatoes, and mango into small cubes and add to the bowl. Add olive oil and hot sauce. Mix again.
Let stand for at least 40 min, up to overnight.
Immediately before serving, add avocados cut into small cubes. Mix thoroughly and service with crunchy tostadas.
Optional: replace the shrimp with the equivalent amount of fish for a fish only ceviche.
