I'm running out of kitchen gadgets to get my dad for Father's Day. Suggestions?

My dad loves to cook, but will only expend the effort to a certain point, hence no fancy baking or fresh pasta. Over the last few years, my mom and I have pooled our money to get him some nice tools and equipment but now I'm running out of ideas!

In past years, he's gotten:

• a Foodsaver

• a meat grinder

• an electric knife sharpener

• some nice chef's and carving knives

• a bread machine

• a le creuset Dutch oven

He makes a lot of casseroles, roasts, grilled foods, and grains. Would it be better to maybe get him some interesting foods to try cooking instead?
