Ingredients
Protein & Base
- 12 oz (340 g) fresh halibut fillet
- 8 (6-inch) corn tortillas, warmed
- 4 large lettuce leaves (optional, for lower-carb version)
Salsa
- 1 large (8 oz) California avocado, diced
- 1 medium pink grapefruit, segmented
- 2 ancho chiles, toasted, stemmed, and seeded
- ¼ cup (15 g) chopped chives
- ¼ cup (60 ml) freshly squeezed orange juice
- 1 tbsp (15 ml) freshly squeezed lime juice
Seasoning
- 1 tbsp (15 ml) extra virgin olive oil
- ½ tsp (3 g) salt
- ¼ tsp (1 g) black pepper
Directions
Prepare the Salsa
- Toast ancho chiles in a cast-iron skillet until softened and aromatic. Slice into thin strips.
- Segment the grapefruit over a bowl to catch the juices, then dice into ½-inch pieces.
- In a medium mixing bowl, combine diced grapefruit, avocado, toasted ancho chiles, and chopped chives.
- Add reserved grapefruit juice, orange juice, lime juice, olive oil, salt, and pepper. Toss gently and let sit for 20–30 minutes to allow flavors to meld.
Prepare the Fish
- Heat a grill pan over medium-high heat or preheat an outdoor grill.
- Drizzle the halibut with 1 tsp olive oil and season lightly with salt and pepper.
- Grill for 2–4 minutes per side, until cooked through and flaky. Break into large chunks.
Assemble the Tacos
- Place a lettuce leaf on each tortilla (if using), followed by chunks of grilled fish.
- Top with a generous spoonful of the avocado, grapefruit, and ancho salsa.
Serve
Serve tacos immediately, with lime wedges for added tanginess. For a lower-carb option, use the lettuce leaves as wraps instead of tortillas.
Make-Ahead & Storage
- Salsa Prep: The avocado-grapefruit salsa can be prepared up to 2 hours ahead and refrigerated. The citrus will help prevent the avocado from browning.
- Fish: Best grilled just before serving, but can be cooked up to 24 hours ahead and gently reheated.
- Storage: Store components separately in airtight containers. Consume within 2 days for optimal freshness.
Diabetic Context
This recipe is carefully designed to provide a satisfying meal without causing dramatic blood sugar fluctuations. The protein from fish helps slow digestion, while the healthy fats from avocado and olive oil contribute to satiety without impacting glucose levels. The fiber from vegetables and limited amount of corn tortillas provides a gradual release of energy. For those seeking stricter carbohydrate control, the lettuce wrap alternative offers a delicious lower-carb option.
