Cook the pasta al dente according to the instructions on the package.
Drain the mushrooms. Put the tomato and rice cuisine in a saucepan, season well with the broth, pepper, salt, marjoram, oregano and thyme and bring to the boil.
Dice the onion, paprika and sun-dried tomatoes.
Put the pasta, vegetables and sauce in a baking dish, mix and sprinkle with a vegan cheese substitute. Bake for about 25 minutes.
With Simply V Vegan Melt Pleasure the casserole tasted really great. If you want to do without ready-made cheese substitutes, you can make a yeast melt or prepare a crust of seasoned nut butter and water.
