This will depend on your nutritional needs and which recipe you choose. Some recipes are more of a "complete meal" while others are lower in calories and good for a snack to help keep your blood sugar stable. Usually if it's 350-500+ calories per serving this would be a meal. Be sure if using as a meal replacement that it contains some healthy fats like avocado and protein (nuts, seeds, powders, etc.) to slow the blood sugar absorption and also to make it more balanced.
