Step 1

Mix all the sauce ingredients in a bowl, except the cornstarch slurry. Feel free to adjust seasoning depending on desired taste. Set aside.

Step 2

Heat a pot with water. Cook pasta until chewy or al dente.

Step 3

While pasta is cooking, heat a pan. Add in 2 tbsp sesame oil. Once hot, sauté the onion and leeks (if using). Add in the garlic and bell peppers (if using) then sauté until tender. Add in the TVP/lentils/mushrooms then sauté for 2-3 minutes.

Step 4

Pour in the sauce and leave to simmer over medium heat.

Step 5

Once the sauce boils, add in the cornstarch slurry. Continuously mix until the sauce starts to thicken.

Step 6

Add in the spaghetti and cook until it has absorbed some of the sauce. Season with a pinch of salt, or more as needed. Mix then turn off heat.

Step 7

Top with some leeks and sesame seeds, if desired. Enjoy while hot!
