I prepare these baked potatoes in a toaster oven. They are the perfect compliment to a hamburger, steak or chicken entree. Try them. You'll like them!

I thought I was doing my kid a favor when I invested in a case of Earth's Best dinners.  Unfortunately, the second ingredient (after water) for all of these is....applesauce.  Or in the case of the "Sweet Potato & Chicken" variety, it's sweet potatoes, followed by apricot puree.  After getting used to the sweetness of these (try 'em - they're like jam), it's difficult for kids to adjust to "real" food.  From now on, I'm going to stick with just pureeing home-cooked food.  It's a lot cheaper, too.

Picked up a few jars of this on closeout at Walmart for a buck apiece.  I love all of the Pace salsas so I figured this would be good as well.  I was wrong.  Disgusting texture, WAY too much salt, stale flavor.  Guess I'll go back to Tostito's brand, which is not very good but a LOT better than than Pace.
