Ingredients
1 small cauliflower (2 pounds), leaves removed
1 serrano chile, seeded and minced
½ cup fresh lemon juice (from 3 large lemons), plus lemon wedges for serving
¼ cup extra-virgin olive oil
2 teaspoons minced nori sheets, nori flakes or granulated kelp
1 teaspoon wakame, minced or crushed (optional)
1 teaspoon liquid aminos or soy sauce
1 teaspoon hot sauce, plus more for serving
Coarse sea salt and black pepper
2 ripe medium Hass avocados, pitted, peeled and cut into ¼-inch dice
1 medium beefsteak tomato, cored and cut into ¼-inch dice
1 Persian cucumber or ½ English cucumber, cut into ¼-inch dice
¾ cup packed finely chopped cilantro
12 corn tostadas or 7 ounces tortilla chips (about 10 cups), for serving
Preparation
- Step 1
Grate the cauliflower against the large holes of a grater, rotating to grate all the florets and stopping at the core. Alternatively, cut off the florets then mince with a knife or pulse in a food processor until it resembles a riced texture.
- Step 2
Transfer the cauliflower to a large bowl and add the serrano chile, lemon juice, olive oil, nori, wakame, liquid aminos and hot sauce. Season with salt and pepper and mix well. Season again to taste; it should be slightly salty. Cover. Refrigerate for at least 30 minutes or up to 1 day.
- Step 3
When ready to serve, add the avocados, tomato, cucumber and cilantro, and mix well. Taste for salt and adjust as needed. Serve over tostadas or with tortilla chips, with lemon wedges, salt and hot sauce.
Private Notes
Comments
We really liked the idea of this. I made the recipe exactly as written, although we ate it as tacos with avocado and tomato as toppings. When I make it again, I will omit the kelp and wakame. It's much better as a vegan riff on tacos rather than ceviche, which honestly I don't think can be improved upon. But we really enjoyed it! So healthy, and vegan, which our over-fished world needs.
Can anyone before I try this tell me why store brought riced cauliflower won’t work?
I agree with Susan. I made it and while I enjoyed the mix on tostadas, it did not suggest ceviche even with the wake error and nori. A great meal, but a different title is needed.
Next time I would hand chop the cauliflower and leave the prices a bit bigger. Wanted more texture. We ate it with chips as a dip.
Meh. A friend made this and loved it, but I did not love it and won't make it again.
Used jalapeños (2) instead of Serrano pepper. We added shrimp—yum and great on tostadas.
