A vibrant and flavorful dish combining seitan with a tangy pineapple sauce and colorful vegetables.
Heat a skillet over medium heat and add a drizzle of oil.
Use a non-stick skillet to prevent sticking and ensure even cooking.
Sauté the onion, garlic, and ginger until the onion becomes translucent.
Stir frequently to avoid burning the garlic.
Add the pineapple chunks, bell peppers, brown sugar, ketchup, and soy sauce to the skillet.
Mix well to ensure the sauce coats all the ingredients evenly.
Bring the mixture to a boil, then reduce the heat to a simmer.
Simmering allows the flavors to meld together beautifully.
Stir in the seitan and the dissolved cornstarch, cooking until the sauce thickens.
Keep stirring to avoid lumps forming from the cornstarch.
Serve the stir-fry over your choice of rice or noodles.
Garnish with chopped green onions or sesame seeds for added flavor and presentation.
