The Pastorelli family moves to California where they become partners in Contadina Canning and help establish the first North American olive-crushing plant, Matmore Olive Oil Company in Lindsey, CA.

After WWII, where many women left the home to go to work, fewer women had hours in the kitchen to spend making homemade sauce, so Leandro Pastorelli, with the help of his sister Mary DiStefano and his brother Mario, formulated the Italian Chef Pizza sauce, the first fully-prepared Pizza Sauce offered in a can.

Pastorelli moves into the plant at 901 W Lake St. where they begin bottling and labeling oils and vinegars for restaurants.
