Here's a dish I threw together tonight that I think turned out well enough to share. I now compulsively photograph everything I cook so even though I didn't know I'd be posting about it until it's done, it's fully documented.
1 tuna steak, about 1/3 pound - cut in 2 inch cubes
1/3 pound extra firm tofu - cut in 2 inch cubes
a few glugs of soy sauce
half as much sake
a generous pinch of brown sugar
finely grated ginger
(obviously, I didn't measure so I'm not going to make quantities up now)
2 scallions, sliced thin - white and green separated
4 leaves bok choy - sliced thin - stem and leaves separated
1 carrot, in very thin strips
squeeze of lemon
drizzle of sesame oil
white rice, cooked however you cook your white rice
1. Mix the marinade ingredients. Add tuna and tofu. Marinate one hour, turning half way through.
2. Drain marinade into a small bowl and set aside. Pat tuna dry.
3. Heat a Tablespoon of oil to nearly smoking in a medium non-stick pan. Sear tuna for no more than 30 seconds, flip and sear again. Remove.
4. Repeat with tofu for about the same time. Remove to bowl with tuna. Keep someplace warm.
5. Add a bit more oil to the pan as the previous Tablespoon is now all over your stovetop, shirt and glasses. Actually, you might want to go wash your face at this point.
6. Give the oil a moment to heat up then add the bok choy stems and the white part of the scallion. Stir fry until wilted. Add the rest of the vegetables. Stir fry briefly. I let the cabbage get a bit browned for some extra flavor, but it's up to you.
7. Remove pan from heat. Crack in the two eggs and stir to lightly scramble. When eggs are not quite dry, remove to bowl.
8. Pack a bowl with white rice. Top with four cubes of tuna and four of tofu. Add a third of the vegetable mixture. Pour a third of the marinade on and finish with lemon and sesame oil.
If you want a proper restaurant-style teriyaki sauce, you'll want to make a bit more of the marinade, bring it to a boil in a small pot, add no more than a Tablespoon of cornstarch (dissolved in cold water) and let thicken. Personally, I didn't want to let everything else get cold while I did that. But if you're keeping everything someplace warm as I suggested above, it would probably be an improvement.
The tuna and tofu absorbed plenty of flavor from the marinade but still maintained their own character and texture. You could use meat or shrimp instead but then you'd definitely want to boil the sauce for a while. Or you could use all tofu. You could mix and match the vegetables, too. Mushrooms or peppers would work well. Maybe even broccoli, but I think that would throw off the quick cooking and you wouldn't the bright fresh flavors I got.
So, quick, easy and tasty. Fresh and fairly healthy. I'm rather pleased with it.
