Grocery Adventures: a minor diversion

Sometimes, when I'm in the grocery store, I look at what other people have in their carts and imagine what they are going to make... or what I could make with what they have. On occasion, this leads to good ideas. Other time, not so much. Yesterday, the woman in front of me in line had nothing but:

1. frozen pie crusts
2. a bottle of hot sauce (a brand I was unfamiliar with)
3. a bag a onions (yellow. maybe sweet. I couldn't tell.)

 Clearly (or so I imagine) these things were meant to be used together in a spicy caramelized onion pie. At a minimum, all she'd need to add would be pantry items like butter and eggs. I'm not the only one who does this sort of thing, am I?
