Part of the health-conscious 'protein' trend in Korean convenience stores targeting gym-goers. - Author: Andrew Lekashman - Tags: South Korea, Japanese Sandos, Convenience Store Sandwiches, #auto-imported **🇰🇷 South Korea** · Family: [Convenience Store Sandwiches](https://onesandwich.com/tag/convenience-store/) · Region: South Korea (CU) · Bread: white-bread · Proteins: chicken --- Ingredients white bread · chicken · lettuce · tomato · mayonnaise The *CU Chicken Breast Sandwich* is a convenience-store sandwich built around grilled chicken breast and vegetables, sold chilled in the refrigerated case at CU, Korea's largest convenience chain. The angle is restraint aimed at a specific shopper. This is the protein-forward, lower-indulgence option in a case otherwise full of egg-mayo and sweet cream sandwiches, pitched at gym-goers who want lean filling and a clean macro profile. It lives or dies on the chicken: kept moist and properly seasoned, it carries the sandwich, but dry or bland and there is nothing rich enough to hide behind. The build is deliberately spare. Soft white sandwich bread, crusts usually trimmed, holds sliced or shredded grilled chicken breast as the main mass. A modest vegetable layer, typically lettuce and sometimes tomato or cucumber, adds freshness and bulk without heavy dressing. The sauce is applied with a light hand, a thin mustard or a restrained mayo rather than the thick sweet spreads on the indulgent sandwiches, keeping the calorie load down by design. The whole thing is sealed in a wedge pack and refrigerated for grab-and-go. Good execution keeps the chicken tender and seasoned enough to taste, the bread soft rather than dried out from the cold case, and the vegetables crisp. Sloppy execution serves chicken that is dry and flavorless, bread that has gone stiff in refrigeration, or so little sauce that the sandwich eats dry and plain. It varies mostly by seasoning treatment and the size of the protein portion across CU's rotating versions. Some runs lean smoky or lightly spiced; others stay nearly plain to keep the profile clean. Limited editions periodically bump the chicken quantity or add a wrap or whole-grain bread to push the health framing harder. It sits within CU's broader sandwich line alongside the classic egg salad and BLT, the lean counterpoint to those richer options, and it shares a case with the chain's gimbap and protein-bar offerings aimed at the same health-conscious shopper. --- ## More from this family Other [Convenience Store Sandwiches](https://onesandwich.com/tag/convenience-store/) sandwiches in South Korea: - [7-Eleven Korea Sandwich Line](https://onesandwich.com/7-eleven-korea-sandwich-line/) - [CU Convenience Store Sandwich Line](https://onesandwich.com/cu-convenience-store-sandwich-line/) - [CU — Egg Salad Sandwich](https://onesandwich.com/cu-egg-salad-sandwich/) - [CU — Ham & Cheese Sandwich](https://onesandwich.com/cu-ham-and-cheese-sandwich/) - [CU — Premium Deli Sandwich](https://onesandwich.com/cu-premium-deli-sandwich/) - [CU — Tuna Sandwich](https://onesandwich.com/cu-tuna-sandwich/) - [Emart24 Sandwich Line](https://onesandwich.com/emart24-sandwich-line/) - [GS25 — Club Sandwich](https://onesandwich.com/gs25-club-sandwich/) [See all Convenience Store Sandwiches sandwiches →](https://onesandwich.com/tag/convenience-store/)
