About 1-inch cubes, 1 lb per pack. From the trimming of the whole beef tenderloin. Tender, mild, and quick to cook.

Sear in a very hot cast iron skillet with butter, salt, and pepper — 2 minutes per side at most. Don't overcook; they toughen fast.
Excellent over egg noodles with a simple mushroom cream sauce, or as a steak-and-potato dinner without the full steakhouse price.
Will last 1-2 days in the fridge once opened. Will last up to 6 months frozen.
