Prep the Ingredients: Rinse and drain the bean sprouts. Cut the tofu into bite-sized pieces if using fresh tofu, or slice the fried tofu into smaller chunks. Prepare the green onions, garlic, and peppers according to the recipe.

Heat the Oil: In a large skillet or wok, heat the canola oil over medium-high heat until shimmering.

Cook the Aromatics: Add the chopped garlic and peppers to the hot oil. Stir-fry for about 30 seconds until fragrant, being careful not to burn the garlic.

Add the Tofu: Toss in the tofu and stir-fry for 2-3 minutes, allowing it to absorb the flavors and brown slightly.

Cook the Bean Sprouts and Green Onions: Add the bean sprouts and green onions to the skillet. Stir-fry for 3-4 minutes, stirring continuously to ensure even cooking.

Season: Drizzle the soy sauce over the stir-fry and toss well to coat. Adjust the seasoning with additional soy sauce or salt if desired.

Serve and Enjoy: Remove from heat and serve immediately. This dish is best enjoyed hot alongside steamed rice or as a topping for noodles.
