We found it necessary to visit our local help and assistance shelter today. They were at closing and going to throw all perishables away. They offered us anything we could use. My husband came away with months worth of tortoise greens! 6 gallons of strawberries, Red lettuce, spinach, spring greens, salads, romaines- a lot of it. Can you all help me find a way to preserve it? Can it be frozen? Chopped and dried?
