12–14 healthy tostada shells, a large bag of tortilla chips, or 12–14 butter lettuce leaves
2 avocados, peeled, seeded, and cubed
Working in batches, use a food processor to mince cauliflower, cilantro, onion, chiles, and garlic. Don’t try to process too much in one batch. Process until vegetables are pea-sized, or use a sharp knife to mince.
Transfer to a salad bowl and toss with tomatoes, lime juice, salt, and pepper.
Cover and refrigerate for 1 hour before serving. Serve on tostada shells, with tortilla chips or in lettuce cups. Top with cubes of avocado.
