Notes
Many overnight oats recipes call for 1-2 tbsp of chia seeds, for 1/3-1/2 cup of oats. Although this isn't a health advice by any means, my recipe calls for a more moderate amount of 1 tsp to factor in daily consumption. Over-consumption of chia seeds could cause issues for some people.Go easy on the matcha if you are new to it (1/2 tsp instead or 1 tsp), as they can be quite strong. Do 1/3 cup rolled oats if you like your overnight oats looser, and 1/2 cup if you need more calories to last till lunch time.
