What kind of beans? I've always liked taking plain pork n beans, adding bacon, some green onions, and some BBQ sauce cooked nice and slow.
Or, there are some good 15 bean soup packages in the stores around here, to which you add a can of diced tomatoes, the juice of a lime (or lemon), diced ham and about a clove of garlic. They can be cooked in a slow cooker and they are awesome.
I second this. Serving in the military, especially now is a noble endeavor, however, it isn't for everybody. Guru is right, make sure this is what you want and have a real clue as to what you are getting into.
