One of my friends, who's vegan, likes to always snack healthy and animal-product-free, which can be difficult when she goes to the movies. To solve this predicament, she brings her own popcorn — topped with olive oil and sea salt — in a baggie in her purse. During the Summer months, with blockbusters galore and the theater's air conditioning calling your name, frequent movie theater jaunts may make for some unhealthy snacking habits. With all the buttery, sugary concession stand choices available, a simple solution may be bringing your own healthy alternatives (like these popcorn ideas). Do you bring your own? Or do you have another way to limit your cal intake at the movies?
