Cook pasta according to package instructions. Drain, rinse with cold water, and set aside.
Turn oven to HIGH broil. Place the red bell pepper halves, skin side up, on a foil lined baking sheet. Press them flat with your hand. Broil on the top rack of your oven for 10 minutes, or until the skins are mostly black. Remove from oven and transfer charred peppers to plastic bag. Close the opening and allow the peppers to steam in the bag for at least 10 minutes.
In the meantime, melt the butter in a large skillet over medium-high heat. Add the onions and garlic and sauté for 2-3 minutes. Transfer the mixture to your blender or food processor.
Remove the bell peppers from the bag and peel the outer blackened skins off the tops of the peppers--they should slide off easily. Add the peppers to the blender. Process everything until smooth.
Pour the mixture back into your skillet over medium heat. Add chicken broth and season with salt, and pepper. Stir in cream. Stir in spinach. Add the cooked tortellini noodles and toss to coat. Add most of the parmesan cheese (reserving a little for topping in each individual bowl). Sprinkle parsley on top.
Make Ahead Instructions: To save time, roast the bell peppers and sauté the onions, garlic, and butter and then blend it all in a food processor (see step 3 of the recipe). Store this mixture, covered, in the refrigerator until you are ready to finish the meal, then cook the tortellini and continue with step 4.Variations:
Pasta: Use any type of pasta you like, including penne and shell noodles.
Veggies: add additional chopped veggies including zucchini, mushrooms or whatever you like. Sauté veggies in step 3 with the onions and garlic.
Chicken: stir in chopped and cooked chicken at the final step of the recipe.
Vegan: substitute vegan butter, vegetable broth, and soy milk or coconut cream for the heavy cream. leave out the parmesan or add 6 Tbs raw cashews, 4 teaspoons, nutritional yeast, 1/4 tsp sea salt, and 1/8 tsp. garlic powder to a food processor, blend until smooth and stir in to pasta in place of parmesan cheese.
