seared tuna steaks with red onion and lime

Start to marinate your tuna steaks at least an hour in advance in the juice of 3-4 limes, a touch of white vinegar, a chopped red onion, some black pepper and a touch of salt. Turn the steaks upside down occasionally and then simply sear in a hot pan with some olive oil. Serve with avocado slices and a light salad. YUUUUUM!
