In this Low FODMAP Gumbo recipe, we use a combination of butter beans, chopped oyster mushrooms, and shredded jackfruit for a touch of meaty texture – but this is really where you can get creative with your favorite plant-based protein, sausage, and seafood swaps based on your tolerance and preferences.   Butter beans are low FODMAP in ¼ cup (35 g) or less and are rich in prebiotic fibers, magnesium, and plant-based proteins. Jackfruit packs a similar nutrient profile, with more fiber and protein than most fruit (more on this below). Oyster mushrooms act as a great substitute for chicken in many plant-based recipes, as they take on a similar texture and mouthfeel and easily absorb surrounding flavors.
