- 2 tablespoons vegetable oil
- 1 package (14 ounces) extra-firm tofu, drained, patted dry, and cut into 1/2-inch cubes
- Coarse salt
- 2 red bell peppers, ribs and seeds removed, thinly sliced
- 1 small head green cabbage (2 pounds), quartered, cored, and thinly sliced crosswise
- 2 garlic cloves, slivered
- 1/4 to 1/2 teaspoon red-pepper flakes
- 2 tablespoon smooth peanut butter
- 1/4 cup soy sauce
- 1/4 cup rice vinegar
- Leftover spaghetti from Tomato-Garlic Spaghetti (http://www.marthastewart.com/262603/tomato-garlic-spaghetti)
- Heat 1 tablespoon oil in a large nonstick skillet over high heat; add tofu and 1 teaspoon salt. Cook,
tossing occasionally, until golden, 8 to 10 minutes; transfer to a plate.
- Heat remaining tablespoon oil in same skillet over medium-high heat. Add bell peppers, cabbage, garlic, pepper flakes, and 1/2 teaspoon salt;
toss to coat. Cover; cook, tossing occasionally, until vegetables are crisp-tender, 8 to 10 minutes.
- Meanwhile, make sauce: In a small bowl (or liquid measuring cup), stir together peanut butter and 1/4 cup hot water until smooth; stir in soy sauce and vinegar.
- Add tofu, leftover spaghetti, and sauce to skillet; simmer until heated through and saucy, 1 to 2 minutes.
When cooked, extra-firm tofu holds its shape better than other types; drain well on paper towels before using.
