Ex Input:
I bought these for my boyfriend who really likes honey roasted pecans in salads that I have at a couple of restaurants. Plus, he likes nuts, pecans, almonds peanuts. He loved these. I actually ordered 3 cans instead of the gift tin, so he could take one to work, or his place, and stay fresh longer. Although I don't think freshness will be an issue, they won't last long......lol

Save your money and do not buy this product. Does not even come close to bacon flavor more like a hickory smoke taste. After everyone in my family tried it we all agreed it was nasty(we're not picky either).

Two words: potato flakes. Not sure what the buzz about these is. Try one bag before you buy a case. Can't be returned.
