"Beef" with broccoli, a simple Stir Fry

This is a stir fry I created with ingredients I already had at home. It was nothing too special but tasty. I started off by slicing thin slices of homemade seitan, using this recipe. The results were good but in the future, I think I will add some whole wheat or chickpea flour to the vital wheat gluten since I prefer a more tender rather than a chewy, rubbery consistency. I used a very small amount of olive oil to heat the seitan slices and then added about 2 cups of frozen stir fry vegetables which were a combination of broccoli, mushrooms, onions and water chestnuts. For the stir fry sauce, I used several tablespoons of vegetarian (vegan to be exact) "oyster sauce". I don't know if it really mimics the taste of oyster sauce. This sauce is mainly made from mushrooms (oyster mushrooms?), water, and seasonings. I found this at an Asian market where I was also able to pick up some other vegan staples at very reasonable prices. I suggest paying one of these a visit to pick up some interesting vegan finds.
