Servings: 1
Prep Time: 10 minutes
Cook Time: 10–12 minutes
Ingredients
Main Dish – Grilled Mackerel
1 mackerel fillet (bones and membrane removed)
Freshly ground black pepper
Dried basil
1 lemon wedge, for serving
Side Dish 1 – Cucumber Sunomono
1/3 cucumber, thinly sliced
1 tbsp apple cider vinegar (rice vinegar for authenticity)
1 tsp alulose or sugar substitute
Pinch of salt (if using)
1 tsp dried or fresh wakame, rehydrated
Bonito flakes (optional)
Side Dish 2 – Boiled Broccoli
1/2 cup broccoli florets
Pinch of salt (optional)
Side Dish 3 – Chilled Tofu
3 small pieces silken or soft tofu
1/2 tsp low-sodium soy sauce or ponzu
1/4 green onion, finely chopped
Grated ginger (optional)
Instructions
Grill the Mackerel
Pat the fillet dry. Season with black pepper and dried basil. Grill skin-side down over medium heat for 4–6 minutes per side, or until the skin is crispy and the fish is cooked through. Serve with a wedge of lemon.
Make the Cucumber Sunomono
In a small bowl, combine vinegar, alulose, and a pinch of salt (if using). Add thinly sliced cucumber and wakame. Let sit for 5–10 minutes. Top with bonito flakes (if using).
Boil the Broccoli
Bring a pot of water to a boil. Add broccoli and cook for 1–2 minutes until bright green and just tender. Drain and set aside.
Prepare the Tofu
Slice tofu into small blocks. Plate and drizzle with ponzu. Top with chopped green onion and a small amount of grated ginger and bonito flakes if desired.
Why It Works
This meal balances heart-healthy fats from mackerel with hydrating and fibrous vegetables. The sunomono provides acidity and crunch, tofu offers protein and cool contrast, and broccoli adds warmth and texture. Light, nutrient-rich, and deeply satisfying.
