Here is a basic recipe for a Ham Panini. I've added some notes at the bottom of the recipe on ways that you can dressed it up a little and make it really yummy.
Ingredients:
- Olive Oil
 - Bread
 - Brown or Dijon mustard
 - Sliced ham
 - Swiss cheese
 
- Preheat panini maker to the medium heat setting.
 - Brush one side of each slice of bread with the olive oil. Put the olive oil side of the bread down on a clean surface.
 - Put a thin layer of mustard on a slice of bread.
 - Place 2 slices of ham on top of the mustard. Make sure that the ham does not hang over the sides of the bread.
 - Add the Swiss cheese on top of the last layer.
 - Place the top slice of bread on top with the oiled side up.
 - Place the sandwich(es) on the panini make and cook until golden and crispy. This should take about 5 minutes.
 
- Instead of using Swiss cheese, use grated Gruyère cheese.
 - Between the ham and cheese layers, add a layer of Béchamel sauce.
