Set oven to broiling.
Slice the red peppers into large chunks, discarding the stem. Place them skin up on a cookie sheet, broil until there are black spots on the skins. This will not take very long once the oven is heated, so keep checking them!
While they are broiling, slice the baguettes in half length-wise. On one slice, apply a thin layer of Dijon mustard, and the other, a thicker layer of mayo. Put the baguette back together, then slather a thin layer of Earth Balance on the outside of the bread, both bottom and top. Toast them over the stovetop on medium heat in a wide, shallow pan, turning over until toasted.
By now the peppers should be ready to be removed from the oven. Once you take them out, place them in a bowl and cover them. The condensation from their heat will soften and loosen their skins. This takes a couple minutes.
While you are waiting, open the baguettes and layer the lettuce, tomatoes (both fresh and sun-dried), and any other vegetable you like!
Return to the peppers, and peel their skins. If they are too hot to touch, you can rinse them with cool water first, peel, then pat them dry with a paper towel. Add them to the sandwich, and press the slices of bread together.
Enjoy!!!
