How do you do dinner?

It's so hard! Mr. Pen works 3 nights a week and trying to keep a-nearly-11-mos-old entertained while preparing a meal is nearly impossible. Cobi can now open cupboards and he throws everything all over the floor, he climbs my legs and won't let go. If I sit him down so I can move, he cries. I've tried baby wearing, but he's in the way if he's in the front - or it's dangerous while cooking, and he doesn't like being on my back because he can't see what's going on.

I choose easy dinners that should take 30 minutes, but it always takes an hour.

Cooking is so much more enjoyable on the weekends when DH plays with Cobi...

How do you guys do it?!
