If you’ve ever heard the expression “easy as pie,” you know that it was coined by someone who eats pie, not someone who makes it. Pie is not crazy difficult to make, but if I had to make up an expression about something being easy, I would not pick pie. Maybe “easy as microwave popcorn?” Nah. That’s hard. I burn it a lot.
Besides, if you’re going for ease, you should probably pick a finger food. Pie is easy to eat if you have plates and forks, but I cannot tell you how often someone brings a pie into the office and there are no implements with which to consume said pie. When given the choice, I turn my pie into bars. And when given further choice, I make lemon pie bars. With endless crumbs on top!
