Cook the noodles: Cook the soba noodles according to the package instructions: it should take about 4 to 5 minutes. Important: when the noodles are done cooking, rinse them under cool running water in a strainer, tossing them to remove the starch. Then shake off excess water. If you’d like the noodles to be warm when serving, run them under warm water for a few seconds; (If you skip this step, the noodles soak up the sauce and become too dry.)
Whisk the sauce: Meanwhile, in a medium bowl whisk together the soy sauce, peanut butter, vinegar, a pinch of sugar, half a clove of grated garlic and chilli.
Cook broccoli: In a separate pot, bring water to boil. Blanche broccoli florets or stems (depending on what you are using) for about 5 to 10 minutes.
Stir-fry: Stir fry tofu cubes in a dry non-stick pan until slightly gold. Add frozen broad beans, a pinch of salt and stir fry until cooked. If needed add a splash of water not to burn the ingredients. Once ready, add cooked and rinsed soba noodles, broccoli florets cut into smaller pieces and toss-up with the sauce you made.
Enjoy warm or cold.
