Stir oregano and red pepper flakes, for spiciness, into chunky vegetable tomato sauce. Add sauce and 1-1/2 cups grated cheddar to macaroni and mix well.
Spoon mixture into a greased baking dish large enough to hold at least 8 cups (2 L). Smooth top. Sprinkle with remaining 1-1/2 cups cheese. Generously cover with foil, sealing well around edges of dish. This casserole is now ready to bake right away, refrigerate for up to a day or freeze.
