Preheat oven to 300F. Plug in a waffle maker.
While the waffle maker is heating up, stir together the pancake/waffle mix, milk, egg and oil a large mixing bowl, making sure not to overmix. Toss in the ham and cheese and give it a stir to combine.
Once the waffle maker is hot, brush it lightly with some melted butter, then ladle about 1/4 cup of batter into the center. Close the lid and cook until the waffles are golden brown and steam has stopped coming out from between the griddle plates, 3-4 minutes.
Place the finished waffles onto a baking sheet lined with a cooling rack and reserve them in the warm oven while you finish cooking off the rest of your batter.
While the waffles are cooking, whisk together the Dijon mustard and honey in a small serving bowl.
Once all the waffles are done cooking, cut each into four sticks. Plate the waffle sticks and pass them at the table with the honey mustard dipping sauce alongside.
