Nordy is right, preparing panini in the morning is your best bet. This way you can control costs and waste a little easier.
In my opinion panini are a great addition to a coffeehouse menu. It would not be uncommon to sell 20-30 a day and at $5-$6 each they can be a great additional profit center.
Here are a few of my favorite recipes:
POMODORO E FORMAGGIO
Vine Ripe Tomato,
Mozzarella Cheese,
& Fresh Basil
POLLO E PEPPERS
Mesquite Broiled Chicken Breast,
Roasted Red Bell Pepper,
Mozzarella & Rosemary
ITALIAN STALLION
Prosciutto, Salami,
Tomato, Grilled Onion,
& Mozzarella Cheese, w/ Oregano
Ok ... this post is making me hungry!
