When they're not in season, you can buy frozen raspberries and use them in smoothies and muffins, or thaw them for yogurt bowls.
Frozen peas are inexpensive and easy to keep on hand; they just need to be thawed and heated before serving as a simple side.
Almost all kids love cereal. A fiber-packed ready-to-eat cereal can deliver anywhere from 3 g to 14 g of fiber per serving.
Lentils, white beans and kidney beans are all kid-friendly (and high-fiber) legumes to try too.
Most kids like the taste, but if yours is averse to avocado's texture or flavor, try blending it into a smoothie for a fiber boost (it also gives the smoothie a super silky texture).
Nuts are also a great source of healthy fats for kids. If allergies are a concern, try sunflower seeds or pumpkin seeds for a fiber and protein boost.
