{"type":"firestarter.listing","listing":{"id":"lst_ZKArTykg","product_name":"Buttercrunch Bibb Lettuce","category":"Vegetables","description":"Bibb lettuce possesses a tantalizing texture: at once smooth and crisp. The round leaves wrap loosely together. A beautiful and fun-to-eat salad can be made by harvesting the whole head and setting the plant in a salad bowl (remove the core first). Toss some shredded veggies and roasted nuts on top, drizzle with dressing, and voila! A true delicacy that far outshines a supermarket salad.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/IMG_4188.jpg?v=1735580498","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/IMG_4210.jpg?v=1735580498","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Buttercrunch-Bibb-Lettuce-vendor-unknown-1630675224.jpg?v=1735580498"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:40.057Z"},"share_url":"https://firestarter.network/l/lst_ZKArTykg","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
