Vegan Everything Bagel Pasta

1 Cook the pasta according to package directions. Drain when done.
2 While the pasta is cooking, in a large non-stick skillet, heat 2 tablespoons of vegan butter on medium high. Once the butter has melted, add the diced onion to the skillet.
3 Saute the onion, reducing heat as needed for 3-4 minutes, or until the onion is translucent. 
4 Then add the remaining tablespoon of butter. Once it has melted, stir the flour into the butter and onions to make a roux(paste). 
5 Cook for a minute, then whisk the non-dairy milk into the onion roux. Whisk until it is fully combined and there are no lumps of flour left. Let simmer for a minute or 2 until it starts to thicken. 
6 Season with a pinch of salt and pepper, then add the vegan cream cheese. Stir the cream cheese into the sauce until it has melted and is fully combined. The sauce should be smooth.
7 Next, add the everything bagel seasoning, stir to combine and then turn the heat off. 
8 When the pasta is done, return it to the pot you cooked it in and pour the sauce over the pasta. Toss to combine. Taste and adjust seasonings.
9 Serve with more everything bagel seasoning on top and green onions or chives if desired.
