This recipe is amazingly delicious, and -very- easy to make! I didn't have any marinara sauce so I created my own using a can of tomato soup and some seaonings (pepper, garlic/onion powder, seasoning salt, flour to thicken). I also only had one zucchini, which made for plenty of leftover stuffing. The microwaving instructions for the squash itself works not only on zucchini, but on zephyr squash, yellow squash, etc - my next attempt will be on scallop squash. Times may need adjusting depending on the size of the squash used, of course.
Again, this was an absolutely amazing recipe. Thank you so much for posting!
