Preheat oven to 375F.
Follow package directions for cooking noodles.
In a medium saucepan combine cool water with the cream soup base and the mushroom seasoning. You can omit the mushroom seasoning if you want.
Heat on low till it reaches the thickness you desire. If too thick you can thin it out with a bit of plant milk.
Melt vegan butter in the microwave. Do in ten-second increments till melted. Mix in the panko crumbs and parsley. Set aside.
Drain noodles and return to pot. Mix in the cream soup, tuna, peas, and cheez. Transfer to a square baking dish. Top with bread crumb mixture, sprinkling on top evenly.
Bake uncovered in a 375F oven for 8 to 10 mins. Enjoy with a nice light side salad and buttered bread.
