These nut-free freezer uncrustables are soft, perfectly sealed, and taste just as good thawed as they do fresh. Made with simple ingredients, they’re a budget-friendly meal prep dream for school lunches.
For best results, use slightly stale bread to prevent sogginess. Toast bread lightly for 30-60 seconds before assembling for a sturdier base. Use room temperature ingredients for easier spreading. Don’t overfill—stick to about 2 tablespoons sunflower butter and 1 tablespoon jelly per sandwich. Press firmly around edges to seal, but don’t squish the center. Double-bag for extra protection if storing more than a month. Label bags with date and filling type.
