Here is a recipe from Barb, that was posted on recipes earlier today.
Nice & Easy Salsa
1 can white shoepeg corn (don't drain)
1 can chopped tomatoes (I like the one with the basil in it)
minced garlic (as much as you like)
1 can of black beans drained
Mix all of the above, then add smooth taco sauce until you get the constancy that you like. If you like it spicier you can add some hot pepper or hot pepper sauce. That's it! Then you serve it with tortilla chips or Frito scoops.
How close will you be to a store? you could pick up some grapes and bananas or something grown locally? strawberries? would just have to eat that day for the berries.
