Preheat the oven to 350 degrees.
Combine 2 cups of flour, salt, 1/2 cup of oil, and 1/4 cup of milk. Roll out the dough.
Grease a muffin pan and line with the pie crust. Make sure to press the pie crust down so that the bottom of the pot pie isn't too thick. Set aside.
Heat the oil in a saucepan over medium heat. Add the onion, garlic, and carrots and cook until transparent and soft.
Add the peas, pre-boiled potatoes, and all of the spices. Cook for 3 more minutes stirring.
Sprinkle with the flour and stir to combine so that the flour evenly coats the veggies. Pour in the water and milk, stirring constantly, and bring to a simmer. Cook until it has thickened. If your vegan pot pie filling doesn't thicken as much, add more flour in 1 teaspoon increments until it is thick. It shouldn't be watery like soup!
Divide the batter between the muffins cups.
Roll out the leftover dough and cut circles into it using the top of a glass, a round cookie cutter, or just a knife. Top your muffin tins with the pie crust circles and pinch the edges to close.
Brush the tops with about 1 Tbsp coconut cream, almond milk, melted vegan butter, aquafaba, or oil, and place them in the preheated oven.
Bake for 35 minutes or until golden brown. Let cool for 10-15 before serving.
