Whisk together 1 cup of vegetable stock, Worchestershire sauce, tomato paste, and cornstarch.

Add the stock mixture to the pan along with the lentils and peas. Turn down the heat and simmer until the mixture has thickened slightly, about 10 minutes.

Stir in the parsley and season with salt and pepper to taste.
