1. In a large skillet, saute onions in oil until softened. Reduce heat to medium-low; cook, stirring occasionally, for 30 minutes or until deep golden brown.
2. Layer the cheese, ham, tomato, pickles and caramelized onions on four bread slices; top with remaining bread. Spread outsides of sandwiches with butter.
3. Cook on a panini maker or indoor grill for 3-4 minutes or until bread is browned and cheese is melted.
