Cook pepperoni in a small skillet until crisp, remove to paper towel to drain.

Melt butter in the skillet and add onion, jalapeño, and garlic, season with salt and pepper and cook just until soft. Let cool.

Combine bread crumbs with cream and let stand until absorbed.

In a large bowl combine meats with remaining filling ingredients, adding cooled onion mixture, soaked bread crumbs and crisp pepperoni finely crumbled.

Add a layer of marinara sauce to prepared pan. You will probably need to use 2 pans to get all the shells in.

Place shells in one layer in prepared pan on top of sauce.

Cover with rest of sauce.

Cover pan with foil and bake 50 minutes.

Remove foil and add remaining cheese, then sprinkle with the italian seasoning, basil and green onion and cook until cheese is melted. About 10-15 minutes.

Serve with remaing sauce on the side. Enjoy.
