Tomasellis at Rosario. Check the catering menu. I've never had their eggplant but everything I've had has been good

Lou Umbertos can hook you up as well. https://www.louumbertositaliankitchen.com/

I didn't check the menus but Luigi's on Hartford Ave and Macera's in Cranston both have catering menus and probably can help you. Maybe Italian Corner in EP or West Vallet Soup and Sauce in West Warwick?
