Place a large pot on a high heat with a small splash of oil. Add frozen beans and cover with a tight fitting lid. Cook for 2 minutes. If they start to burn reduce the heat.

Stir the beans well then cook covered for another minute or until the beans are no longer frozen. Transfer the beans to a clean bowl.

Return pot to the heat and cook meat, stirring until the meat is no longer pink.

Return the beans to the pan and stir in the pesto. Remove from the heat. Taste and season with a little salt if needed.

Serve beans with parmesan on top.
