Italian-style ceviche with citrus-cured fish and olive oil. This high protein mediterranean dish is a fresh, light family appetizer perfect for a healthy, weight loss, or keto approach.
Cut the fish fillets into bite-sized cubes, about 1/2 inch, and ensure all pieces are uniform for even curing.
In a glass bowl, combine lemon juice, orange juice, sea salt, and black pepper; add fish cubes and mix gently.
Cover and refrigerate for 20–30 minutes, stirring halfway through; check the fish turns opaque for proper curing.
Slice cherry tomatoes and red onion thinly, chop basil and parsley; prepare vegetables and herbs while fish cures.
Remove fish from fridge, drain excess marinade, and gently mix with tomatoes, onion, basil, parsley, and olive oil; serve chilled or at room temperature.
