Serves 6-8 as an appetizer.
Juice of 1/2 lime
1 tsp sambal oelek
1 tsp reduced-sodium soy sauce
1/4 tsp kosher salt
1 large red or green scallion, minced
1 avocado, diced
1/2 lb chilled sushi-grade tuna, diced
2 tsp chopped fresh cilantro leaves
In a mixing bowl, combine lime juice, sambal, soy sauce and salt. Add remaining ingredients, and toss to coat.
The lime juice will begin to "cook" the fish, so make this at the last minute. Serve immediately, while still cold, with crackers, toasted bread slices, or in lettuce leaves.
