Cooking Steps

Prep
1

• Bring a medium pot of salted water to a boil. Wash and dry produce. • Halve, peel, and thinly slice onion. Halve, core, and thinly slice bell pepper into strips. Using the tip of a spoon, remove and discard black gills from undersides of mushrooms; trim any large stems if necessary. Thinly slice mushrooms into strips (if strips are too long, cut them in half crosswise).

Make Sauce
2

• In a small bowl, whisk together honey, miso sauce concentrate, half the soy sauce, half the vinegar, half the Szechuan paste (use more for more heat), and 1⁄4 cup water. (For 4 servings, use all the soy sauce, all the vinegar, and 1/3 cup water.)

Cook Veggies
3

• Heat a large drizzle of oil in a large pan over medium-high heat. Add onion, bell pepper, and mushrooms; cook, stirring occasionally, until softened and lightly browned, 5-7 minutes. • Stir in Szechuan sauce mixture; cook, stirring occasionally, until sauce has reduced and slightly thickened, 1-2 minutes.

Cook Noodles
4

• Once water is boiling, add noodles to pot. Cook, stirring occasionally, until al dente, 5-7 minutes. Drain.

Finish Lo Mein
5

• While noodles cook, roughly chop peanuts. • Add drained noodles to pan with veggies; toss until noodles are thoroughly coated in sauce. Taste and season with salt and pepper if desired.

Serve
6

• Divide lo mein between shallow bowls. Top with peanuts and serve.

Review summary

Updated on Dec 2025
  • Flavor: Many loved the sweet-spicy sauce; some found it a bit bland and added extra seasoning or spice for more kick 🌶️.
  • Ease of prep: Quick and simple to make, though some felt veggie chopping took longer than expected.
  • Suggestions: Consider adding protein like tofu, chicken, or shrimp; try red bell pepper instead of green for better flavor.
  • Portions: Several wished for more noodles or a larger serving size; adding extra veggies helped bulk it up.
  • Vegetables: Portobello mushrooms were a hit; some suggested including more varied veggies like carrots or snow peas.
