In a medium size pan saute veggies in olive oil until tender. During this time mix all the dressing ingredients in a medium size bowl.
Slice panini's horizontally. Spread each slice with the chipotle-lime dressing. On one side spread the guacamole. Place veggies and 3 slices of Provolone on sandwich.
I don't have a panini maker so I used a George Forman. This works well. Grill on the Forman for about 8 minutes.
You could add any veggies. Some add mushrooms and asparagus. I just used what was in my fridge. :)
