Healthy Tomato Red Pepper Soup Meal Prep and Storage

Meal Prep – Cook the soup and then allow to cool completely. Scoop single servings into individual containers, or family sized servings into gallon freezer bags (or jars/containers with lids). 
Frozen Soup – Be sure any container is only filled 2/3 full as the soup will expand in the freezer. Store for up to a month in the freezer. If freezing gallon bags, lay flat to freeze to save storage room. 
Refrigerated Soup – Will hold in the refrigerator for 4 days.
Reheating – Add to a medium or large sauce pot, heat frozen for 30 minutes on low, or defrosted soup for 5-10 minutes over medium-low heat.
