Cut zucchini into fourths, creating wedges that are about 3-4 inches long
Using a spoon, scrape out the inside of each piece of zucchini, creating a "boat" to hold the filling
Reserve 1/2 cup of zucchini insides and mash it in a bowl with a fork
Preheat oven to 350 F
On a foil-lined baking sheet, place zucchini boats hollow-side up and drizzle with olive oil, sea salt and a smidge of Italian seasoning
Bake for 15 minutes, or until zucchini is par-cooked
While the zucchini is cooking: In a medium skillet, drizzle a tiny amount of olive oil and cook garlic, onions, zucchini filling and bell peppers until tender
Toss in sausage and allow to cook for a few minutes
Remove from heat and add in bread crumbs and Parmesan cheese - stir until well combined
Once zucchini is done, remove from oven and fill each boat with sausage filling
Top with extra cheese if desired
Cook in oven for an additional 10-12 minutes, or until cheese has melted
Enjoy!
