The Kokoro Grilled Musubi Classic Egg is a frozen 8-pack of Hawaiian-style musubi at Costco, with fluffy egg, premium rice, and a meatless patty wrapped in roasted seaweed and brushed with a sweet-and-savory glaze. It is fully cooked, so it heats in about 75 seconds in the microwave, making it one of the easiest grab-and-go snacks or quick breakfasts in the freezer aisle. If you like easy Asian-style frozen bites, it fits right in next to the Costco Sushi Bake and the Bibigo Kimchi and Cheese Filled Rice Balls.

What musubi is
If you have never had it, musubi is an iconic Hawaiian handheld snack: a block of rice and protein, brushed with a sweet-savory glaze and wrapped in roasted seaweed. The classic version uses Spam, but Kokoro's uses a plant-based meatless patty plus a layer of fluffy egg, so it is a lighter, meatless take on the island staple.
One minute to breakfast
The whole appeal here is speed. You cut a corner of the package, microwave for 1 minute 15 seconds, let it stand a minute, and eat. The rice stays soft, the egg is pleasant and fluffy, and the glaze gives it that familiar sweet-salty flavor.
The meatless patty is savory and holds together well. It is genuinely satisfying for how fast it comes together, and the seaweed wrap keeps it tidy enough to eat with one hand on a busy morning.
Price check
The 8-pack runs around $16.99 to $17.49 at Costco (item #2017338), or roughly $2.10 per musubi. That is the one knock: some shoppers feel it is a touch pricey for a rice-and-egg snack. But for a fully cooked, handheld meal that is ready in under two minutes, the convenience is real, and it is cheaper than grabbing musubi from a shop.
The numbers
Nutrition snapshot (per 1 piece / 120g, 8 servings per pack): 230 cal · 7g fat (1g saturated, 0g trans) · 35mg cholesterol · 680mg sodium · 36g carbs · 4g fiber · 4g sugar (3g added) · 7g protein. Notable: meatless (plant-based patty), with a surprising 4g fiber. Allergens: soy, wheat, and egg. Product of Korea.
The sodium is on the higher side, which is typical for the glaze and seaweed, so pair it with something fresh. Otherwise it is a reasonable 230-calorie snack with a little fiber and protein.
Who'll love it
This is for busy mornings, lunchboxes, and anyone who loves musubi but wants a meatless, grab-and-go version. It is great for quick breakfasts, after-school snacks, and on-the-go bites. Skip it if you have a soy, wheat, or egg allergy, if you are watching sodium, or if you want the classic Spam flavor.

Verdict
A Buy for the convenience, with one eye on the price. Kokoro's egg musubi is a fast, tasty, meatless take on a Hawaiian classic that makes a genuinely easy breakfast or snack. It is a little pricey per piece and the sodium is high, but for a fully cooked handheld meal in under two minutes, it earns a spot in the freezer, especially on hectic mornings.
