A couple non-traditional favorites:
Greek lunch - Mix cannellini and kidney beans (drain and rinse first) with a jar of pesto for the base. Slice some hard salami. Have a bunch of condiments - feta, hummus, cucumbers, tomatos, red onions, marinated artichoke hearts, olives. Pita bread to hold it all.
Mexican wraps - Mix canned chicken (or fresh if you can) with pinto, black and kidney beans and a package of taco seasoning. Have tortillas, sour cream, cheese, black olives, onions, salsa and hot sauce.
"Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover." - Mark Twain
