Prepare the pasta shells as instructed on the package.
In a medium-sized pan, heat olive oil over low heat and add chopped red onions.
Season the onions with salt, pepper, and brown sugar, then let them caramelize for 40 minutes, stirring occasionally.
Add spinach to the onions and cook for an additional 5-10 minutes on low heat.
In a separate medium-sized bowl, combine parmesan, mozzarella, egg, salt, and pepper.
Once the onions and spinach are cooked down, add them to the bowl and mix all ingredients together.
In an oven-safe dish, coat the bottom and edges with olive oil and butter.
Spoon a layer of Organic Roasted Red Pepper and Almond Pesto Sauce onto the bottom of the dish.
Begin stuffing the pasta shells with the mixture from the bowl and place them in the dish.
Once all shells are stuffed, sprinkle with additional parmesan cheese.
Bake in the oven at 375°F for 40 minutes.
Make sure to stir the onions occasionally while caramelizing to prevent them from burning.
Use fresh spinach for the best flavor, but frozen spinach can be substituted if needed.
For an extra cheesy dish, add more mozzarella on top before baking.
Let the stuffed shells rest for 5 minutes after baking to allow the flavors to settle.
