Author Profile Jason Hollins I’m Jason Hollins, and for me, food has never just been about what’s on the plate. It’s about what surrounds it the memories, the people, the sense of place. That belief is what led me to open Osteria Rusticana. We didn’t set out to impress with flash or trend-chasing. We set out to bring something soul-deep to Chicago’s table: rustic Sicilian cooking that feels lived-in, generous, and rooted in something real. By 2025, something shifted for me. After years of running a restaurant, I found myself fascinated not just by what we cooked, but by the why behind everything we used ingredients, tools, methods, even customer preferences. That curiosity pushed me to explore beyond the kitchen. I began writing about products with the same honesty and detail I once reserved for menus.
