Paninis Don’t Need Meat To Be Hearty And Filling. You Just Need The Right Combination Of Vegetables, Gooey Cheese, And Seasonings. If You Don’t Have A Panini Press To Create That Distinctive Crunch On The Outside, You Can Use An Electric Skillet And Cook One Side At A Time. Be Sure You Use Something To Weigh Down The Paninis As They Cook. That Compression Is Important For The Finished Product! Try Placing A Heavy Frying Pan On Top.
