Serves 4

Salt
8 ounces each: broccoli crowns, cut into small florets, and sliced mushrooms
1/2 box (8 ounces) spaghetti
7 to 8 ounces drained extra-firm tofu (1/2 package), cut into bite-size chunks
1 tablespoon low-sodium soy sauce
1 recipe Lo Mein Sauce (see below)
2 tablespoons vegetable oil
1 medium-large onion, halved from pole to pole, each half cut into sixths
1 tablespoon each: fresh garlic and ginger

Bring 2 quarts of water and a generous sprinkling of salt to boil in large pot. Add broccoli; cook until crisp-tender, about 2 minutes. Transfer to a plate with a slotted spoon. Add spaghetti, cook, stirring frequently, until just tender; drain and set aside.

Toss tofu with soy. Mix Lo Mein Sauce.

Meanwhile, turn on vent fan and heat a 12-inch nonstick skillet over high heat until very hot. Add 1 tablespoon of oil and the onion; stir-fry until crisp and spotty brown, about 1 minute. Add mushrooms; stir-fry until just cooked, about 2 minutes. Add tofu; stir-fry until lightly browned, about 1 minute longer. Add broccoli; cook until heated through, about 1 minute. Add garlic and ginger; stir-fry until fragrant, about 30 seconds. Transfer to a plate and add remaining 1 tablespoon of oil to the empty skillet; heat until shimmering. Add spaghetti; stir-fry until heated through, about 2 minutes. Return meat/vegetable mixture to pan, along with Lo Mein sauce; stir-fry to combine. Serve immediately.
