Rehydrate soy curls according to package or place in hot water for 5-10 minutes. Strain out the water and squeeze out any excess liquid it absorbed. On a chopping board, roughly chop into bite sized chunks. You can also pull apart with your hands if that is easier.
In a small sauce bowl - mix vegetable broth, hoisin sauce, soy sauce, and sugar together. Whisk until well combined. Add cornstarch and mix until it is fully dissolved.
Heat a sauté pan and coat with about a tablespoon of oil in medium high heat. Sauté aromatics such as onions and garlic. Season with a pinch of salt & pepper. Toss the bay leaves with the aromatics. Sauté until fragrant.
Add the soy curls into the pan and sauté until edges are slightly golden brown. Lower down the heat to medium low and let it sit for about 1-2 minutes. Then, gradually pour the sauce into the soy curl mixture. Do not pour all at once as it may dry out too quickly. Stir and let it simmer for 4-5 minutes or until sauce has thickened or coated the soy curls.
Turn off heat and let it sit to cool down.
