If you are ever around wolf and central, stop in to the Salerno's on Wolf and Kingston. You can get a hefty deli sammich with some interesting choices like roasted peppers, artichokes, shaved prosciutto etc (PLEASE get a side of pesto mayo!) and one of their daily pasta specials for under 10 bux. It's pretty good stuff for what it is, and for the price.
On a side note, for a NOT so healthy burger alternative, in Des PLaines, there is a Las Asada's just south of the motorcycle dealership on Rand and river - just north of the old mcdonald's. If you've never had a real char grilled skirt steak taqueria experience, PLEASE give it a try. Don't expect white table cloths here, it's just a joint that knows how to grill up some steak. If you like steak tacos / burritos though, this may be a bad choice, since I've never known anyone to not get HOOKED for life on this place. I'll never go back to the pan fried chewy steak that most of the Chicagoland taco places dish up.
We cannot be friends if you do not know the difference between Mayo and Miracle Whip.
