{"type":"firestarter.listing","listing":{"id":"lst_AvH_OMvV","product_name":"Batavian Full Heart Escarole","category":"Vegetables","description":"Escarole is a slightly bitter green in the chicory family. It resembles lettuce, but packs plenty of vitamins and minerals, making it a great choice for the health conscious. Escarole prefers cooler temps, so grow it in early spring or late summer for fall harvests. The hearts, served with a warm dressing and caramelized walnuts and onions, make a delicious salad. Cooked escarole pairs nicely with beans for a warming fall soup. The flavor is best after frost.","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/products/BatavianFullHeartEscarole_34_1.jpg?v=1735579927"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:39.425Z"},"share_url":"https://firestarter.network/l/lst_AvH_OMvV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
