FYI, Grinder Kits come "unassembled" -- for you neophytes, at least the buns are pre-sliced. Everything else is in a nice little tub with a Red Pepper logo lid or in plastic wrap. Here are the steps to recreate near-University Ave. perfection in the privacy of your own kitchen:
1) Heat the taco meat in a microwave-safe bowl for about 30-45 seconds, stirring once or twice (better yet, heat in a non-stick pan on the stove);
2) While the taco meat is heating, layer the lettuce (sans plastic bag and twistie) on the lower half of the bun(s) on top of a paper plate;
3) Add some hot sauce (to taste) and some of the white sauce (NO, it is NOT just plain MAYO, sheesh!) from the containers provided on top of the lettuce;
4) Layer the non-taco meat (did you order turkey, salami, ham, or all three as an "everything" grinder?), then the cheese(s) -- the white slabs, then the colby for you "both cheeses" types -- on top of the lettuce/hot sauce/white sauce base;
5) GENTLY spread the warmed taco meat on the cut side of the TOP half of the bun(s);
6) Flip each taco-meat laden bun top onto the bottom and heat in the microwave for 50-90 seconds on high, preferably in a really dirty microwave (recent chili-heating duty is a nice touch). Be certain to check to see if the top is "hot" -- but not too hot -- to touch after about 45 seconds. The proper amount of radiation IS the key to proper flavor melding! "Nuke it" is the technical ordering reference in person, folks!
Sit down and wish you were actually at the original University Ave. location (or the "upscale" 42nd Street location if you are taking Grandma and Grandpa -- nice job of getting the old "feel" in a new structure). Just don't think about how much that 4-pack Grinder Kit package you had FedEx'ed to you REALLY cost! Think of it as a Happy Meal that you bounced a check for!
How easy was Christmas shopping for YOUR Fighting Sioux fans/UND alums on the list this year, eh?
-- Eatin' at the Pepper for 40 years and still diggin' it (as is my spouse and 12-yr-old child!).
