Tuna Steak with Mango & Onion Salsa

Published on 6 July 2026 at 07:42

A smart, stylish twist on lean luxury

This dish is the perfect example of how clean eating doesn’t have to mean boring eating. It’s bright, fresh, and packed with the kind of flavour that makes healthy food feel indulgent. Think of it as beach‑body cuisine — light, high‑protein, and bursting with tropical energy.

The Concept

Tuna is the heavyweight champion of lean protein — rich in omega‑3s and low in fat. Pair it with a zesty mango and onion salsa, and you’ve got a plate that’s equal parts nutrition and sophistication. The citrus‑soy marinade gives the fish depth, while the salsa adds a punch of colour and sweetness that screams summer.

Ingredients

  • 125 ml light soy sauce

  • 125 ml orange juice

  • 1 tsp sesame oil

  • Juice of 2 limes

  • 350 g fresh tuna steaks

  • 1 red onion, finely sliced

  • 1 ripe mango, cubed

  • 150 g rocket or baby spinach leaves

Method

  1. Marinate with intent. Combine soy sauce, orange juice, sesame oil, and lime juice in a bowl. Pour half into a separate dish and add the tuna steaks. Chill for at least 30 minutes — overnight if you can — to let the flavours sink in.

  2. Cook off for perfection. Heat a non‑stick pan or grill until hot. Cook the tuna for about 1 minute per side for that perfect pink centre. Slice against the grain into thick, elegant strips.

  3. Build the balance. Stir the sliced onion into the remaining sauce to create a quick salsa. Lay rocket or spinach on each plate, top with tuna slices, and spoon the mango‑onion mixture over the top.
