I've had the seared tuna in nice restaurants, but this is better than all of them. One tablespoon of wasabi sounds like a lot of heat, but somehow this cooking method mellows it to almost nothing, just leaves the flavor. Really really great.
For a quick and flavorful classic, saute bacon or pancetta and add onions, garlic and red pepper flakes. Cook with canned plum tomatoes for a mere 10 minutes, stir in fresh parsley or basil and toss with cooked spaghetti. Pass the Parmesan and enjoy!
