Preheat oven to 350 degrees F. Trim ends of zucchini and cut in half lengthwise. Using a spoon, scoop out the flesh from each half. Chop the zucchini flesh and reserve. Place zucchini boats in a 9x13" baking dish.
In a large nonstick skillet, heat oil on medium-high. Cook onion, garlic, and chopped zucchini flesh 5 minutes, until softened. Add sausage and lemon juice. Season with salt and pepper. Cook on medium-high 8 to 10 minutes, until browned, breaking up meat with a wooden spoon. Remove from heat and stir in pesto.
Spoon pesto sausage into zucchini boats. Sprinkle breadcrumbs and feta crumbles over top of each. Bake 20 to 25 minutes, until golden.
