Parmesan cheese is such a bold flavor, you only need 1/4 cup to add a big punch to this vegetarian toaster-oven sandwich. Get a serving of fruit too, when you enjoy the sandwich with a fresh pear.
Lay bread on work surface. Spread avocado on one slice. Top with tomatoes and sprinkle with cheese. Toast both pieces of bread in a toaster oven until the plain piece is toasted and the cheese is starting to melt on the topped piece, 4 to 6 minutes.
Remove the toast from the toaster oven with a spatula, and mound greens (or spinach) on top of the cheese side. Drizzle with vinegar and top with the remaining toast. Cut in half if desired and serve with pear.
