Preheat the oven to 375°F. To make the stew, heat olive oil and vegan butter in a large saucepan. Add onion, carrot, celery, and a pinch of salt, and cook over medium-high heat until just tender, about 10 to 15 minutes. Add the cubed seitan, and cook for a couple minutes more. Sprinkle the flour over the vegetable-seitan mixture, and stir well to coat. Cook for another few minutes, stirring constantly to prevent burning, until flour is lightly browned and smells toasty. Add the vegetable stock, non-dairy milk, thyme, nutritional yeast, salt, and pepper and bring to a boil over medium-high heat, stirring frequently. Stir in the frozen peas. Reduce the heat to low, cover the pot, and simmer gently as you prepare the biscuits.

To prepare the biscuits, mix together the flour, baking powder, baking soda, salt, and sugar in a large bowl. Add the vegan butter and use pastry cutter, or twi knives to work in the butter until it resembles small pebbles. (Alternatively, you can use a food processor.) Use a spatula to fold in the “buttermilk” and parsley, and knead briefly in the bowl, adding extra flour as needed to keep dough from sticking. Turn the dough out onto a lightly floured surface, and roll into a circle roughly half an inch thick. Using a biscuit cutter or a narrow drinking glass, cut out as many biscuits as you can. Re-roll the dough and continue making biscuits until you’re out of dough. You should have between 10 and 12 biscuits using a 3-inch biscuit cutter.

Place biscuits on a parchment-lined baking sheet. Use a pastry brush to brush each biscuit with a small amount of non-dairy milk. Bake the biscuits for 25 to 30 minutes, until baked through and starting to brown. Remove biscuits from oven and split in half for serving. To serve, ladle the hot stew over a split biscuit.

Note: For a one-dish meal, bake biscuits on top of the stew. To do this, instead of simmering the stew, pour into an oiled 9-inch by 13-inch baking dish, top with the uncooked biscuits, and bake for 25 to 35 minutes, until biscuits are browned and stew is bubbling.
