The Sweet Potato Sandwhich

I am currently trying to get my son to from fry land to sweet potato. I am losing.... But here is another idea..... one can of sweet potatoes.. One can of pineapples....drained... one bag of small nuts... one tsp of olive oil.... In a pan, take the sweetpotatoes with olive oil. Add pineapples ....Then spread nuts. You can season with cinannmon and spread like peanutbutter....
