Vegan Cheeseburger Hamburger Helper Stuffed Shells

1 First, cook the shells according to package directions.  Drain and set aside to cool off enough so you can handle them. 
2 Now, using the same pot if you want. Heat the olive oil on medium high. Then add in the mushrooms and garlic. Saute the mushrooms, reducing heat as needed for about 5-6 minutes until they have released their liquid and it has cooked off. Season with a bit of salt and pepper. 
3 Then, pour in the TVP, soy sauce and liquid smoke. Stir to combine everything with the mushrooms and garlic. 
4 Next, add the veggie broth. Cook for 1-3 minutes, stirring, until all of the broth has been absorbed by the TVP and it is no longer dry. Taste and season with a bit more salt and pepper. 
5 Now, you can either set the TVP/mushroom mixture aside and get a new pot for the cheese sauce, or remove the TVP/ mushroom mixture from the pot scooping it into a mixing bowl and use the same pot for the cheese sauce. 
6 Once you have removed the TVP/mushroom mixture from the heat either way, make the cheese sauce. Start by melting the vegan butter in a pot on medium low. 
7 Then whisk in the flour. Whisk until fully combined, cook for a minute or two until the butter/flour mixture(roux) is thick. Now pour in the almond milk and whisk until the roux has been fully combined with the almond milk. 
8 Now add in the mustard, whisking, then the nutritional yeast, turmeric and garlic powder. Add a pinch of salt and pepper. Whisk to combine. Simmer on low for a minute or 2 until the sauce is nice and thick. Taste and adjust seasoning. 
9 Now, preheat the oven to 375 degrees. 
10 Pour half the cheese sauce into the pot or bowl with the TVP/mushroom mixture. Stir to combine. Then take you cooled pasta shells and fill each one with a little bit of the "cheeseburger" mixture. Placing each one in a baking dish. 
11 Once you have all the shells filled, pour the remaining cheese sauce over the shells and bake at 375 for about 5-7 minutes until everything is nice and hot. 
12 Top with chopped parsley if you want, and serve immediately!
