Served at room temperature on a warm day or served warm on a cool late summer evening, this Red Pepper Soup with Grilled Cheese Croutons is an easy and healthy vegetarian lunch or dinner option for every season!

Tomatoes seem to get all of the love at this time of year (and I certainly appreciate a good Gazpacho), but we can’t forget about the sweet, crisp bell peppers either! Unlike the strong garlic and spice in a chilled gazpacho; this particular soup is mild and creamy — making it appealing to just about everyone.
It gets a rich, deep flavor from the roasted red peppers, which is perfectly accented by the crusty, sharp, cheesy croutons bobbing on top!

Is Red Pepper Soup Healthy?
Yes! It’s like a grown-up twist on the classic tomato soup + grilled cheese combo…in a very nutritious, fresh, and delicious kind of way!
Best of all, this satisfying and filling meal only requires a handful of simple (REAL FOOD) ingredients and about 15 minutes of hands-on time. The soup itself keeps really well in the refrigerator or freezer, so feel free to prep ahead and enjoy it when the mood strikes!
For less than 250 calories, you can have your filling soup, your comforting grilled cheese sandwich, and a very full belly!
Make it Spicy
Give your red pepper soup a spicy kick by adding in some fresh chili, red pepper flakes or even some paprika or cayenne pepper. It’s easy to adjust the spiciness to your liking, for a big punch of heat go for the fresh chili but for something more subtle just add a pinch of one of the spices above.
