Ten Don (Tempura Donburi) - 天丼 [Y3K Recipes Issue No. 55] _ Leftover Tempura? No worries, use them all in this easy quick meal. In fact, this is one of T's favorite dishes. He always asked me to prepare a lot of tempura so he can have tempura-don the next day. The very first tempura-don I had was cooked by him, I was still new to Japanese cooking then.
