Birdies Cofounders Bianca Gates and Marisa Sharkey Share Their Must Haves

Sharkey's go-to snack is the 365 by Whole Foods Market Mango Slices Organic ($8). In fact, she loves it so much, her team got her a near-lifetime supply of it. "They have a really good, unique taste that's tangy and not very sweet, which is what I like," she says. This specific brand of dried mangos is organic, vegan, and kosher, with no added sugar, and Sharkey says these have the best consistency and stay the freshest.
