Gently squeeze as much liquid out of thawed tofu as possible. Cut tofu crosswise into 1/2-inch thick slices, then diagonally, to make 4 triangles. * Combine marinade ingredients and mix well. Arrange tofu triangles in one layer in a dish and cover with marinade. Allow to sit for at least 10 minutes to absorb the flavours. Prepare sauce mix by combining all ingredients in a small bowl. In a separate bowl mix the water or stock and the 1 tsp. cornstarch. Dredge marinated tofu pieces in cornmeal or cornstarch and fry over medium heat in 1/8 to 1/4 inch of oil, for 3-4 minutes on each side. Drain and keep warm in 200F oven.
Add leftover marinade to sauce mix. Heat 3 T. oil in a wok. Stir-fry garlic and onion until onion is tender. Add greens and continue stir-frying until just wilted but not mushy. Add sauce mix and cornstarch mix and stir-fry just until sauce is thickened. Add reserved fried tofu. Serve with rice.
* I cut the tofu into many more smaller triangles.
