In a bowl or pan mix together the flour, salt and pepper, and lightly dredge each chicken saltimbocca in the flour and pat off any excess and set aside.
Add the olive oil to a large saute pan over medium heat and cook the saltimbocca in batches prosciutto ham side down first for 2 ½ to 3 minutes per side or until browned and cooked through out.
