Feel free to customize this salad based on your dietary preferences or what you have on hand. For a gluten-free option, substitute the spaghetti with gluten-free pasta, quinoa, or even spiralized vegetables like zucchini or carrots. If you're looking to amp up the protein, consider adding grilled chicken, shrimp, or chickpeas.
For a burst of extra flavor, try incorporating some fresh herbs such as basil, parsley, or cilantro. If you enjoy a little heat, a dash of crushed red pepper flakes can kick up the spice level. Vegan? Skip the Parmesan or use a plant-based cheese—this salad is versatile enough to fit various diets and preferences.
