Ingredients

Instructions

  1. Step 1: Cook 8 oz soba noodles in a large pot of boiling salted water for 5-6 minutes until tender but firm. Drain and rinse under cold water to stop cooking and cool the noodles.

  3. Step 3: Heat 3 tbsp vegetable oil in a large nonstick skillet over medium-high heat. Add coated tofu cubes and fry for 3-4 minutes per side until golden and crispy. Remove and drain on paper towels.
  4. Step 4: In a medium bowl, whisk together 1/4 cup creamy peanut butter, 3 tbsp soy sauce, 2 tbsp rice vinegar, 1 tbsp honey, 1 tsp sesame oil, 1 tbsp sriracha, and 1 tbsp fresh lime juice until smooth and creamy.
  5. Step 5: Toss the cooled soba noodles with the peanut sauce until evenly coated. Plate the noodles and top with crispy tofu, 2 thinly sliced green onions, and 1 tbsp sesame seeds for garnish.
