Preheat your oven to 350°F (175°C). Slice each croissant in half horizontally and place cut side up on a baking sheet. Toast in the oven for about 5–7 minutes until golden brown.

In a medium mixing bowl, combine shredded cooked chicken with your choice of Caesar dressing. Mix well until the chicken is evenly coated and set aside.

Layer a generous handful of romaine lettuce on the bottom half of each croissant, followed by spooning the Caesar-dressed chicken over the lettuce.

Top with additional vegetables such as sliced tomatoes, cucumbers, or avocado.

Close the sandwich by placing the top half of each croissant back on, gently pressing down to secure the ingredients. Wrap in plastic if making ahead.

Serve immediately for the best flavor and freshness, alongside a light salad or crispy potato chips.
