I love my food processor. It's a 14 cup Cuisinart and I use it surprisingly often. It's expensive though. I just bought a 4 cup mini one and love it too, and it's much less expensive! Great for mincing garlic, making small batches of pesto, spreads, rubs, marinades, etc. Also great as a spice grinder
Other things I have and love:
Immersion blender
Le Creuset dutch oven
Really nice salt and pepper mills
Crock pot! I love my crock pot, and a really good crock pot cook book is "Not Your Mother's Slow Cooker Cook Book"
