I'm not one to combine pb and bananas with jelly (Now Nutella! That's another story!) but some friends go together like that, just a little on the edge.
Don't let anyone tell you that you can't combine foods you love to create a delicious chimera. For instance, one of the best burgers I've ever eaten had peanut butter, bacon and a fried egg on it. Sounds bizarre, tastes AMAZING. Also, it was the only thing I ate that day, talk about a calorie bomb!
