Green Olives

Hi everyone! I am new to the forum, so I apologize if this is a “noob” question. I really love green olives as a topping, but I have found it hard to find pre-sliced green olives without pimentos that would work well for a pizza. Papa Murphy’s has my favorite “chain” green olives (I really think they are great), but I also cannot find ones that are similar to those. Anyone have any recommendations for where to look? Thanks for your help!
