Prepare your pie crust according to recipe or package instructions. Grease or line a 9-inch pie pan and par-bake the bottom crust. Keep the top crust chilled until just before baking in step 6. Preheat the oven to 425°F.

Whisk flour, nutritional yeast, salt, and milk together in a small saucepan over medium-high heat. Bring the mixture to a simmer, then reduce heat to medium and simmer for 3 minutes, whisking constantly, until sauce thickens. Set aside; sauce will thicken further.

Melt butter in a large sauté pan with a lid over medium heat. Add onion, celery, and carrot; sauté for 3 minutes until onion is translucent. Add garlic, thyme, smoked paprika, and black pepper; sauté for an additional 2 minutes to toast spices.

Add potatoes to the pan and mix well. Add 1/4 cup water to the pan, cover, and cook for 5 minutes to steam the potatoes.

Uncover pan and add chickpeas and peas. Mix well, then turn off the heat. Stir in prepared sauce and mix until evenly distributed.

Roll out top pie crust according to recipe instructions. Transfer chickpea filling to par-baked crust, then top with the remaining crust. Use a fork to crimp edges together, and cut an 'X' in the center of the pie dough for ventilation.

Bake on the middle rack of the oven for 15 minutes. Check crust; if golden, loosely tent with foil to prevent burning. Bake for an additional 10-12 minutes, checking every 5 minutes, until crust is golden brown.
