I usually don't do expensive kitchen stuff...or anything for that matter...but my mom-in-love gave me a Pampered Chef Mix and Chop and I use it at least 4 times a week.
I love this tool. I use it to chop ground beef. It makes it quick and easy. Without must effort at all it help you ground your beef into tiny bits. A few of the meals I use this tool for are: Baked Ziti, Taco Soup, spaghetti, enchiladas, Beefy Cheese Dip, and Mexican Trifold.
I have bought one of these (and the other pampered chef tools I love) off eBay for my mom. Love'm
*Note: I am not being paid for these recommendations/reviews but if you know how I can- bring it!
