Melt butter in a medium saucepan on a medium high heat. Add frozen peas and cook, covered for a minute. Stir and cook for another minute or until peas are hot and no longer frozen.

Remove from the heat and stir in chicken and mint (if using). Taste and season remembering the olives and cheese will add more salt.

Divide between two big bowls. Scatter over cheese and olives and enjoy!
