Onions...

Why is it that the past two days I have made some excellent dinners (pasta carbonara and this Salmon dish, but with orange juice instead of apple cider) that did not need any onions, went grocery shopping yesterday and didn't realize I needed to buy onions and now every possible dinner I can think of (including our planned meal, Pulled Pork) requires onions?

Why Why Why?!

Now I am paralyzed with indecision...what in my million recipe books can I find that's yummy and doesn't require onions (or anything else I don't have)? Should I really take the girls out shopping when it's -20C out and we have no other need to go out today? It's not impossible but also not desirable.

Tell me this kind of thing happens to you all too. =)
