Cook the pasta to VERY al dente in salted water, about 3 minutes less than the minimum time on the package. Drain and set aside, reserving some pasta water if using.
In a large bowl, combine the pasta and the rest of the ingredients with all but a handful of the grated cheese. Taste the mixture and add more of the spices to your preference. It will be slightly soupy and weird because the veggies are raw, but should still taste good!
Transfer the mixture to a large baking dish, 9x13 or so, and top with the rest of the cheese.
Bake at 375F for 20-30 minutes until hot and bubbly. Let rest for 5 minutes before scooping into shallow bowls. Enjoy!
Notes
To make-ahead, do everything but the final baking step. This can be frozen for several months, then baked from frozen (start in a cold oven, turn to 375F) or thawed in the oven overnight. This can also be kept in the fridge for a few days prior to baking and serving.If you don't have seasoned salt, kosher salt works fine in this dish!
