Bring the slices together and, if you have a panini press, simply place your paninis in and push down. Generally, about 3-4 minutes should be enough.
If you don’t have a panini press, don’t worry! It’s very easy to make the paninis in a pan on the stove over medium-high heat. Simply place the paninis in the pan, and press them with a heavy item of cookware, such as a large cooking pot, or with a chef’s press (if lucky enough to own one). Cook for about 5 minutes, flipping the paninis midway through the cooking time.
