Creating Fiber-Rich Salad Blends

To really maximize your fiber intake, try mixing together different types of lettuces and leafy greens.

Adding shredded cabbage or spinach to your salad base can instantly take the fiber content even further, making your meal even more satisfying and nutrient-dense! The possibilities are truly endless, so don’t be afraid to mix things up as much as you’d like!
