Rough chop shrimp into small pieces

Place shrimp in square container. (Preferably a lasagna one)

Squeeze lime juice over shrimp and let sit for about 30 mins. The lime will cook the shrimp.

Small dice the tomato, cucumber, jalapeño, serrano and onion. Add the mix to the shrimp.

Once shrimp has achieved a pinkish color, add salt and pepper to taste.

You're ready to enjoy your ceviche. I prefer eating on a tostada with some ketchup and hot sauce. (try Salsa Huichol)
