Chia Oatmeal. Chia seeds absorb water or milk, so they’re a great way to thicken up a bowl of oatmeal while also adding some filling fiber. You can mix a tablespoon of seeds directly into your cooked oats, or “gel” them first by allowing them to soak up ¾ cup of milk or almond milk. (Not an oatmeal fan? You can also sprinkle chia seeds over cold cereal or yogurt for a breakfast boost.)
