Clean the wok with a piece of kitchen paper (be careful, it's hot), put it back on the stove, add the remaining 2 tablespoons of oil and lightly sweat all the vegetables in it for approx. 1 min. Then immediately deglaze with the marinade, turn the heat down halfway and let it simmer gently for 2 minutes. In the meantime, stir in some starch mixed with water to make the sauce shine. But that in small quantities and steps. You don't want the sauce to be pudding-like. After the 2 minutes have elapsed, fold in the meat, turn off the heat and let the vegetables simmer with the remaining heat inside. Just try a piece.
