Not to worry! You can still get your bread golden and crispy in a pan. If possible, use a weight to press down the sandwich to replicate the panini press. A good, cheap option I always keep on hand is a brick wrapped in foil. Sometimes I also use my marble rolling board and stone mortar-pestle. If you’re looking for a lower fat version, you can simply toast your bread in a countertop toaster and omit the butter. While it is still good, though, the butter does make a big difference!
