Creating freezer croissant sandwiches that don’t get soggy is a simple process. Follow these easy steps:

1. Prepare the Croissants: Slice each croissant in half horizontally to create a top and bottom.
2. Mix the Filling: In a bowl, combine the shredded chicken, cheese, spinach, tomatoes, and mayonnaise. Season with salt and pepper. Mix until well combined.
3. Fill the Croissants: Generously spoon the filling onto the bottom half of each croissant. Spread it evenly and cover with the top half.
4. Wrap for Freezing: Individually wrap each sandwich in plastic wrap or aluminum foil. This helps prevent freezer burn and keeps them fresh.
5. Freeze: Place the wrapped sandwiches in a freezer-safe bag or container. Freeze for at least 1-2 hours until solid.

Your freezer croissant sandwiches are now ready to be enjoyed whenever you like!
