Canadian Bacon and Havarti Cheese Sliders with Pesto Glaze from The Food Charlatan. Who doesn’t love a good ham and cheese sandwich? Especially when it is upgraded with Canadian Bacon, Havarti cheese, a buttery pesto glaze, and baked to hot cheesy perfection? These are my new favorite appetizer!…or lunch. Or dinner! These would be great for gamy day or for summer BBQs!
