Grilled tuna steaks

This was completely my husband's dish. I don't eat seafood and I totally dislike how it smells and tastes. I know I  know, it's really good for you. But hey, I can't help it. Although these did look good and I had to snap a pic real quick. Here's how he made them:

Tuna steaks - 3

For the marinade:

Chilli powder - 1 tbsp

Lemon juice - 2 tbsp

Salt - to taste

Turmeric - 1 tsp

Tandoori masala - 1 tbsp

Oil - 1 tbsp

Mix all the ingredients for the marinade and apply on the fish. Marinate for a couple of hours and grill them for about 5 minute on each side. Serve with lemon wedges and onion rings.
