Butter 1 side of 4 of the bread rounds.
Place the soup cans on a cookie sheet lined with parchment paper. Place the buttered bread round, buttered-side up, in each can. Spoon 2 tablespoons of strawberries with liquid to cover over each round. Dredge 1 side of 4 bread rounds in the strawberry liquid and place over the strawberries. Repeat layering strawberries and dredged bread rounds until you have 3 layers of strawberries and 4 layers of bread.
