Brown Sausage: Heat a Dutch oven over medium-high heat. Add the Italian sausage and cook, breaking it up, until browned, about 6–8 minutes. If there’s a lot of grease, carefully spoon off excess.
Cook Carrots: Stir in the diced carrots and cook for about 2 minutes to start softening them.
Add Onion, Celery, and Pepper: Add the diced onion, celery, and bell pepper. Cook, stirring, until the vegetables begin to soften, about 3 minutes.
Add Sauce and Broth: Pour in the pasta sauce and chicken broth, then stir well to combine everything into a soup base.
Stir In Pesto: Add the sun-dried tomato pesto and stir until it’s fully blended in.
Simmer and Cook Ravioli: Bring the soup to a gentle simmer over medium heat. Add the mini cheese ravioli and simmer until tender, about 5–7 minutes, stirring occasionally so nothing sticks.
Preheat Oven and Prep Peaches: Preheat the oven to 375°F. Peel and slice the peaches and set them aside.
Spread Cinnamon Butter: Lay out the crescent dough triangles. Spread a thin layer of cinnamon butter over each triangle.
Fill and Roll Crescents: Place peach slices on the wide end of each triangle, then roll up into crescents. Place on a parchment-lined baking sheet.
Bake Crescents: Bake at 375°F until puffed and golden brown, about 10–12 minutes. Serve warm alongside the soup.
