Example Input: ...........but still not that great. It's bland. Even when I added salt, pepper, milk, and butter, it didn't taste like the best I've had. But at least it's edible, unlike every other canned clam chowder out there. If I can find a way to make this taste better than I'd love it. It's the best CANNED clam chowder I've ever had, but it's not that great. The clams taste good.  EDIT: I had a 2nd can and I made it today, I added only a little bit of milk and I added NO salt, pepper, or butter, and it actually tastes a lot better than when I did. So I suggest adding nothing but some milk or cream to this soup. It's still not the best I've ever had though.

Example Input: Riba foods based in Houston, Texas makes this awesome black bean dip. It is pretty much all natural and without the lard that regular refried bean dip has in it. I am not sure why in Dallas TX it's so hard to find - maybe because Riba has SO Many good flavors??? I make the traditional 7-layer dip with this instead of the refried beans, and am thinking about creating a breakfast quesadilla with this and some verde sauce. Try it, it's not too too spicy but is very good!

Example Input: This is a very tasty product. Tastes more like tuna. However I believe the 35mg of salt listed on the indgredients for a 1/4 cup serving is much lower than the actual salt content. I use very little salt and these are somewhat salty. I also opened a can of Crown Prince natural brisling sardines in water which has a salt content of about 45 mg. The crown prince tasted much less salty than the Roland sardines. So I think Roland needs to be a little more careful about their packaging and list of ingredients. My guess is the salt content is comparable to a can of water packed tuna, maybe 210 mg or higher per 1/4 cup serving.
