🧄 Very useful ingredient notes
- Tostada shells - store-bought, look for oil-free baked ones or make your own tostada shells at home in the oven or air fryer)
- Heart of palm - look for it in a jar or can. Heart of palm texture and color serves as an excellent vegan alternative to seafood, such as scallops or white fish in this ceviche dish. Heart of palm has a very mild flavor and is tender to the bite without cooking it.
- Avocado - look for avocados that are ripe but not mushy
- Dulse flakes - Dulse is a type of seaweed. The tiny brown flakes have a mild seafood flavor. You don't need much. This gives the dish a hint of ocean or sea flavor. It's optional, but I highly recommend it.
📋 Substitutions and variations
- Heart of palm - Substitute with extra avocado, chopped cauliflower, chickpeas or cubed tofu (soya)
- Dulse flakes - If you can't find dulse flakes (I got mine at Whole Foods), you could possibly substitute it with 1 teaspoon of other tender seaweed, like:
- a sprinkle of vegan furikake rice seasoning
- minced nori
- finely crumbled or minced seaweed snacks
- minced wakame seaweed that has already been rehydrated in water
- minced seaweed salad
- a dash of vegan fish sauce
Here are some ideas for alternate versions:
- Serve with tortilla chips, plantain chips or saltine crackers instead of the tostada shells
- Add jicama or red bell pepper for some crunch

❓ FAQ
Vegan ceviche with heart of palm and avocado can be stored in the refrigerator for up to 2 days. Store tostadas separately, at room temperature, in an airtight bag or container. But, ceviche really is best eaten right away.
No, it is not, because it contains seafood. However, you can make a vegan version of ceviche using heart of palm and dulse flakes that is delicious!
🗺 Cultural influences
Ceviche, a cold seafood dish where the fish is "cooked" by the acid in the lime juice, originates in South America, with Peruvian ceviche considered to be the original.
It is often served in a glass cup or bowl with plantain chips, sweet potato (in Peru), saltine crackers or tortilla chips.
