Like sex or a good accountant, a breakfast burrito is one of those things you don't give much thought to until the first time you have it, and afterwards you wonder how you ever lived so long without it. Happily, there are about 17 million places in Denver where you can get a breakfast burrito. And while almost all of those breakfast burritos are the same -- eggs, potatoes, cheese and meat wrapped in a flour tortilla -- Sam's No. 3 offers a surprise variation. Its corned-beef-hash breakfast burrito is as big as a fat kid's forearm, stuffed dangerously full of scrambled eggs, sliced potatoes and chunky corned beef; and upon request, the whole thing will come smothered in Sam's tame green chile, which serves to keep everything soft and warm and gloppy no matter how long it takes you to work your way from one end to the other.
