Bake or grill the patties and fries.
Toast the bread, cut up the leek and salad.
Spread vegan butter on the bread and spread on the tomato sauce and pesto.
Sprinkle on the salad and leek, put the pattie on and put the second slice of bread on top, and spread butter and put on some more pesto :) Add the fries and your ready to go!
We usually have dressings to match, garlic and thousand island, to dip the fries in :)
Hope it tastes great!
