This attractive stir-fry is inspired by a traditional Chinese dish called rainbow beef. The vegetarian version works well, and it’s also easier to make. If you prefer a very firm tofu, take the extra time to weight it as directed in step 1. I am happy to skip this step and use firm tofu that hasn’t been weighted.
Mix together 1 tablespoon of the soy sauce, 1 teaspoon of the brown sugar and 1 tablespoon of the oil in a medium bowl. Toss with the tofu, and stir to make sure all of the pieces are coated. Let sit for five to 10 minutes while you prepare the other ingredients.
03In a small bowl, stir together the remaining soy sauce and sugar, hoisin sauce and sesame oil. Set aside.
04Heat a large nonstick skillet or wok over high heat until a drop of water evaporates on contact. Add the oil, turn the heat to medium-high and add the peppers. Stir-fry for a couple of minutes, until the peppers begin to soften, and add the garlic and ginger. Stir-fry for 20 seconds, until the garlic and ginger begin to smell fragrant, and add the tofu, dried red pepper flakes and green onions. Stir-fry two minutes, give the sauce a stir and add to the pan. Cover and cook for three minutes. Remove the lid, stir the ingredients in the pan, and taste and adjust seasonings. Serve with rice or noodles.
