On a Roll Sandwich Shoppe in Carlsbad has served a weekday lunch following on Loker Avenue West since opening in 2018, specializing in made-to-order deli sandwiches and breakfast items. The roast beef comes directly from Tip Top Meats on Paseo Del Norte — the German-heritage butcher supplying several North County delis — while the turkey breast is fresh, skinless, and center-cut. Signature builds include the nine-inch Ultimate, the Reuben on rye, the High Roller, and the Palermo Italian with grilled chicken and salami, all constructed on bread delivered and sliced in-house. The morning menu runs breakfast burritos, croissants, and English muffin sandwiches alongside the lunch program, covering the same pre-work and midday slots that fuel Carlsbad's Loker Avenue industrial corridor near Steady State Roasting. Corporate catering assembles ten-sandwich variety trays with same-day turnaround, building custom protein-and-bread combinations across a menu of twelve-plus standard meats and six cheese options.
