Add in shredded chicken and sliced peppers and stir-fry for a few minutes to bring the flavours together. Season with salt and pepper. Garnish with coriander leaves and set aside to cool.
Preheat oven to 375 degrees. Separate croissant triangles as directed. For each triangle, roll out dough to expand a little in size, while keeping the same triangular shape.
Fill each triangle with a heaped spoonful of the cooled chicken filling on the flat end, and roll the triangle as directed by the instructions to form a croissant shape.
Bake for 15-20 minutes till lightly browned and done.
