In a large saucepan over medium heat while the tortellini cooks, heat the olive oil over medium heat. Add the diced tomatoes, spinach, garlic, Italian seasoning, salt and pepper. Cook and stir until the garlic is fragrant and the spinach is wilted.
Stir in the half and half and parmesan cheese. Whisk in the flour to help thicken the mixture.
Drain the tortellini and add it to the spinach mixture. Stir until tortellini is coated and mixture is heated through. Serve warm.
Notes
The great thing about this recipe is how customizable it is. Some other variations we enjoy include the following: add baby portobello mushrooms, substitute spinach for another green vegetable (peas, asparagus or kale), add in roasted red peppers or sautéed onion, add in additional protein (we love shrimp or grilled chicken), substitute a lighter milk (like 2%) for the half and half – the sauce may be a little thinner, but it will still taste good, or fresh tomatoes for the canned.Recipe slightly adapted from All Recipes.
