A parmesan-rind snack. I walked samples into stores unannounced, and into the Roblox and Deloitte office pantries the same week. Offices went from zero to the highest-margin line.

Offers from Eataly and DeCicco's. The company rang the Nasdaq bell, and we filmed a MrBeast feature. If you work at Roblox, Deloitte or Snowflake, you may have eaten it.
