Cashew Pasta Bake

From Z FaMiLy ReCiPe bLoG

OK, I just made this recipe again tonight and realized it isn't strictly vegan with the butter and cheese.  These can be easily substituted for vegan ingredients, or you can settle with being 85% good like I did. 

2 1/2 cups dried penne or other pasta
dash of olive oil, plus 2 TB
2 TB butter
1 onion, chopped
2 cloves garlic, pressed
2 tsp dried oregano
1/2 lb mushrooms, sliced
14 oz can diced tomatoes
1 heaping TB tomato paste
3/4 cup roasted cashews
1/2 of a small zucchini or yellow squash sliced
salt and pepper
3/4 cup grated cheddar cheese

Boil pasta and dash of oil for 10 minutes. Drain. Return to pan and stir in butter. Keep Warm.
While pasta is cooking, preheat oven to 400 degrees. Heat remaining oil in large frying pan and saute' onion, garlic and oregano for 3 minutes. Add the sliced mushrooms and zucchini or squash and continue cooking for 5 minutes, stirring occasionally. Stir in diced tomatoes and tomato paste. Cover and cook for about 10 minutes, stirring occasionally.
Add cashews and season with salt and pepper. Transfer to greased shallow oven proof dish. Spoon the buttered pasta on top and sprinkle with grated cheese. Cover and bake for 20 minutes. Cheese will turn crisp and golden.
Serve with freshly grated parmesan cheese.
