Preheat the broiler.
In a toaster, toast the bread until evenly browned all over. Top each slice with 1/4 C of the baked beans.
Cover with thick slices of Roma tomatos. Drizzle with vegan worcestershire sauce, then sprinkle with the shredded cheeses.
Top with green onions (scallions) and broil until golden and melted.
Garnish with chopped parsley, if desired.
