Bread used to nourish us. Then it was industrialized, ultra-processed, and stripped of nutrients. We built One Mighty Mill to bring back the old way— stone-milled bread and bagels that are full of flavor and nutrition. We start with healthy soil and organic partners farmers, then stone-mill whole grains to bake bread, bagels and tortillas that’s better for people and the planet. Goodness Set in Stone. 📍Available at Whole Foods, Sprouts, Walmart, Target and Costco www.onemightymill.com
