Seeds

Because seeds can behave quite differently (as you'll discover when you add water to chia seeds), unless you enjoy experimenting in the kitchen, you're better off sticking to a recipe. Flax, chia, sesame, pumpkin, sunflower, and hemp hearts are all excellent sources of omega-3 fatty acids. Depending on the texture you want, you may want to leave some of the seeds whole. You can achieve the desired texture by using eggs, olive oil, and small amounts of gluten-free flour. For best results, pre-bake the crust, or if you're handy with a dehydrator, consider using it to make your seed crust.

Many people make delicious rectangular pizza crusts from ground golden flax seeds, but the product also contains soy flour, which may be off-putting to some. Meanwhile, Mauk Family Farms sells raw vegan crusts made from sprouted sesame seeds, sunflower seeds, and flaxseeds if you want to make individual mini pizzas.
