This is a Quesadilla icon. It looks like a slice of pizza except there is a squiggly line where the crust is and instead of circles for pepperoni there are just three horizontal lines.
This Quesadilla icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 5,500 icons, all in the same style and quality.
