Heat olive oil in a large skillet over medium heat. Add sliced onions and reduce heat to medium.
Cook onions for 15-20 minutes, stirring frequently. Continue to cook onions until they begin to soften and turn golden in color.
Reduce heat to low and stir in pepper, beef base and water; stir.
Cook just until liquid has absorbed and onions begin to thicken. Remove from heat.
Heat a grill pan over medium high heat. Butter one side of each bread.
Place two slices of bread, buttered side down on hot grill pan.
Divide onion mixture between both slices of bread, top with cheese and remaining slice of bread; buttered side up.
