I've found in my travels that it still is possible to get a tasty, filling prepared lunch for under $5.00. Here are some of my favorites (prices include tax):

California/Nevada/Arizona: In-N-Out Burger #3 combo, $4.16. Freshly made burger and fries along with a soda. A zillion times better than McDonald's or Burger King because it's much fresher, with quality ingredients.

Richmond, Virginia: Ukrop's supermarket, chicken quesadilla combo, $4.66. Ukrop's, a locally-owned upscale supermarket chain in Richmond and Fredericksburg, has an excellent café at many of its locations. They'll make pretty much any lunch food to order, including this excellent quesadilla: chicken or steak and fresh vegetables grilled inside a whole wheat tortilla, with generous portions of salsa, guacamole, and sour cream, as well as a side of homemade chips and a medium soda with free refill. The quesadilla, as well as many sandwiches, are available with chips and drink for under $5.00.

Charlottesville, Virginia: Asian Express, lunch special, $4.65. This hole-in-the-wall on West Main Street, near the University of Virginia, has a wide selection of Chinese and Japanese menu items available at this price, including rice, egg roll, and a can of soda. Asian Express is the least greasy Chinese restaurant I've found in Charlottesville, and they use more desirable cuts of chicken than some of the other Chinese places here...all for a very low price. Dinner specials are $1.00 more. Web site, with menu is available at www.newasianexpress.com.

What are some other "cheap but good" places around the US, or around the world, serving under-$5.00 lunches?
