Italian Stuffed Zucchini

Saw a recipe very similar to this online. I'd credit the original (or post it in a link) if I could find it again. This isn't exactly it, but...the same basic idea. Tweak it to your own taste.

Ingredients
3 medium zucchini
24 oz marinara
1 T olive oil
1 lb ground beef
½ C onion, chopped
2 garlic cloves, minced
½ bell pepper, chopped
½ tsp each: basil, oregano, thyme
¼ tsp crushed red pepper flakes
¼ C chopped italian parsley
salt & pepper to taste
1 to 1½ C shredded mozzarella
½ C shredded parmesan
¼ C Italian seasoned bread crumbs

Directions
Preheat oven to 350°.

Trim zucchini ends and scoop out centers, leaving about a ¼-½" thick 'shell'. I used a Parisian scoop (melon baller). Chop scooped out centers; set aside.

Place zucchini into baking dish with ½" of water; cover with foil and pre-cook 15-20 minutes. Remove from oven and carefully pour off excess water; set aside.

Photos: I only made a half recipe.

Brown beef, onion, bell pepper and garlic in a skillet with olive oil. Drain off excess grease. Add chopped zucchini centers, 2/3 (approx 16 oz) of the marinara, basil, oregano, thyme, red pepper flakes. Simmer 15-20 minutes, stirring occasionally.

Pour remaining marinara in bottom of baking dish. Place zucchini 'boats' on marinara in baking dish. Scoop beef & veggie mixture into scooped out zucchini, dividing it evenly. I had extra filling -- no problem if it fills in around the edges too! Cover with foil; bake for 20-25 minutes, until zucchini is tender.

While they're cooking, toss chesses and bread crumbs.

Remove stuffed zucchini from oven. Set oven to broil; remove foil and top stuffed zucchini with cheese and bread crumbs. Return to oven just long enough to melt and brown cheese & bread crumbs.
