I tested this one on my twin 10-month old babies and they liked it immediately.  It was their first beef and their first spinach.  I had already given them chicken and they really like it so they are not vegetarians yet anyway.  Mostly I wanted this product for the spinach and the higher iron content.  Somehow they made this particular flavor brand tasty for babies.  I like getting these by the case rather than buying them a jar at a time at the store since 2 babies eat so much.  It's good to keep several flavor brands around too I think, to give your baby a variety.  I'm sure I'll get another case when this one is finished.  Ingredients per the label: Water, Organic Carrots, Organic Finely Ground Beef, Organic Spinach, Organic Garbanzo Bean Flour, Organic Tomato Paste, Organic Whole Durum Wheat Flour. CONTAINS: WHEAT.  This has 110 calories, 31% protein, 100% vitamin A, 8% vitamin C, 4% calcium and 4% iron.  I've been informed that the percentage of daily needs met is based on an adult.

I was amazed at how good this is for canned fruit (which I normally won't touch).  In particular I adore papayas and mangos.  The fruit juice instead of syrup is also very nice.  The easy pull-top on the can makes this a great item to stash in my desk drawer at work, so that I can have a fruit snack easily even if I was too busy or forgot to bring lunch.  So far I haven't gotten a can that had any problems.  The watermelon isn't crunchy - of course not! - but it's good, and certainly not "slimy".
