Panini is the plural form. It would have been a peanut butter and banana panino.
That said, try my latest development, Panino Del Monte Cristo.
Two slices of bread of choice
two slices of Black Forest ham
two slices of roasted turkey breast
two slices of swiss cheese (with holes)
one large egg
1/4 cup egg subsititute
Heat griddle, cast iron griddle pan, panini press, or a George Foreman grill (my personal weapon of choice). Scramble egg and egg substitute together. Dip each slice of bread in egg mixture, turning once. Cook one side of both slices of bread on griddle surface until browned. Turn one slice of bread over, add ham, turkey, and swiss cheese, then top with second slice of bread, uncooked side up. Close press or GF grill, and cook until browned. If using griddle and weight, apply weight to top of panino until browned, then turn over and repeat, if required. Cut panino diagonally, dust with powdered sugar, and serve with large dollop of strawberry preserves.
Excellent accompaniment would be a mixed berry salad with honey yogurt dressing and a strawberry flavored beverage, such as a Strawberry Julius or my aforementioned My Lady's Kiss cocktail, or maybe a glass of Strawberry Quick if you're so inclined.
