Use 2 tablespoons of chia to thicken a bowl or cup of soup. Just let the soup cool down for a few minutes and stir in the chia seeds. Add a half avocado in small cubes to your soup and enjoy a delicious meal packed with protein and fiber. Chia is a great ingredient to thicken soups, gravies and sauces. Remember that the more chia and the more time the chia spends in the liquid the more dense it will get. So experiment. Also remember, not to overheat your chia-thickened recipes to enjoy all the nutritional punch of chia.
