Smart for Life - Edamame Protein Puffs - High Zero Sugar Soy Protein Isolate Puffs 1LB - 20 Grams Snacks - Non-GMO, Gluten-Free, Vegan - 1 Pound Box - 18 Servings

I like millet as an oatmeal substitute! It has a kind of sweet nuttiness that I think works. Good cooked with some dried fruits. Not as much protein or fiber, but easy to digest. Add chia seeds and hemp seeds for fiber and protein. For granola bars and such you would need to buy a puffed cereal like puffed sorghum or millet. They also make quinoa flakes you can use, but I don’t think they are a 1:1 equivalent. There’s also these soy protein puffs that are common in granola bar type protein bars. https://a.co/d/04OhtJlT
