Summer in Southern Arizona is in full swing, and local fields are overflowing with vine-ripened tomatoes, sweet-smelling basil, and enough garlic to make Italian grandmas swoon. Celebrate summer's sweet and spicy bounty at Heirloom Farmers Markets' Tomato Basil & Garlic Festival on July 28 at the Oro Valley Farmers Market (10901 N. Oracle Rd.) and July 29 at the Rillito Park Farmers Market (4502 N. 1st Ave.) from 8am - 12pm. On Sunday at Rillito Park we'll be featuring Executive Chef Ryan Clark from Casino Del Sol's PY Steakhouse as our Chef at the Market ! Taste how Chef Clark celebrates the season with a bowl of his Tomato-Basil-Garlic Gazpacho with Barrio-basil croutons, garlic oil, and sprouts.
