• Using a rounded teaspoon or melon baller, scoop out insides of zucchini leaving a wall that's about 1/4 inch thick. Put all of the zucchini you scooped out in a food processor. 
  
• Add mushrooms, onion, and bell pepper to the zucchini in the food processor. Pulse until you achieve somewhere in between a diced and chopped size. Add garlic and pulse once more to combine.
  

In a large saute pan, cook ground pork over medium high heat. When it's about halfway in between raw and dark and crumbly, add all of the veggies from the food processor. Stir well to combine and continue cooking until the meat is crumbly.

• While the sausage is cooking, preheat the oven to 400 degrees F.
• Add the zucchini boats to a baking sheet. Fill with sausage mixture. Cook in preheated oven until heated through, about 10-20 minutes.
