The sausage and zucchini cook way down in a flavorful (yet simple) marinara sauce for this Italian-inspired meal. Serve it with a fresh green salad on the side.
Heat a Dutch oven or very large skillet with cooking oil over medium heat. Add sausage to heated oil and cook, breaking sausage apart, until browned and cooked through, 8 to 10 minutes. Drain off any excess oil.
Add zucchini and cook for 2 to 3 minutes to get zucchini started cooking.
Add garlic, Italian seasoning, red pepper flakes, and tomato paste, stirring to combine.
Add tomato puree and stir well to combine. Reduce heat to low-medium to prevent the sauce from boiling. Cover and let sauce simmer until zucchini is very tender, 8 to 10 minutes more. (Note: You’ll want this to thicken up, so if the sauce has a lot of liquid, leave it to simmer uncovered so it reduces.)
Taste sauce and season with some salt and pepper.
Toss together bitter greens (if using), baby spinach, oranges, and sunflower seeds. Add vinaigrette until dressed to your liking.
Serve sausage and zucchini with salad on the side. Enjoy!
