Baked beans are classic picnic food and great - provided you know how to make them - and it isn't difficult, expensive or time consuming. Here's the basic recipe...it's for a huge batch so, proceed with caution...

1 gallon prepared baked beans (Cambell's Pork & Beans, etc.)
1 extra large yellow onion, chopped fine
12 ounces dark brown sugar
1/2 cup yellow mustard
1 3/4 cups ketchup, plus more for garnish
Salt
Pepper
5 strips uncooked bacon

Preheat oven to 360 degrees F.

Combine beans, onions, brown sugar, mustard, ketchup, salt, and pepper in a large baking dish. Lay bacon strips across top of beans. Squirt ketchup in a zig-zag pattern across the top of beans and bacon. Bake, uncovered, for 1 hour and 45 minutes.

Note: The above is from a recipe on the FoodTV web page. My mother made them pretty much the same way for decades...though she used less ketchup and did not "zig zag" it across the top. Definately use the bacon - you may not want to eat it (I do but I'm weird) but it does season the beans really well. Finally, I would never make this size batch for a pic nic or pitch-in because you will not be the only one bringing them and the less you bring, the less chance of having to drag the leftovers home.
