A recipe for delicious seared tuna with sauce that I just invented and cooked in about 5 minutes:
1 lb tuna steak (ahi tuna is only $5/lb at Trader Joe's in DC)
1 tsp powdered ginger
1 tsp powdered garlic
3 tbsp melted butter (unsalted preferably)
1 tbsp soy sauce
1 tbsp lime juice
just a little touch of horseradish to taste
Sprinkle ginger and garlic on tuna. Sear the tuna on very high heat for just 1 minute on each side so that it is still RAW in the middle but slightly crispy on the outside like delicious tuna steak should be. Meanwhile, mix the sauce ingredients together.
Serve the tuna with sliced AVOCADO and drizzle the sauce on it. Delicious!
