Tomato, Cheese, And Avocado Sandwich - cooking recipe

Ingredients

2 2 slices potato bread or 2 slices whole grain bread (what-have-you)
1/2 teaspoon mayonnaise (Best Foods, Hellmann's, or Vegenaise)
1/2 teaspoon Dijon mustard
2 -3 drops balsamic vinegar, to taste
1 slice provolone cheese
1 slice prosciutto or 1 slice ham (an extremely thin slice) (optional)
1/2 ripe avocado, pitted,peeled,and in slices
4 slices ripe tomatoes (thin slices)
salt & freshly ground black pepper, to taste (I like a tri-color pepper mix)
1 leaf romaine lettuce or 1/4 cup alfalfa sprout (I often leave this off)

Preparation

If you like your sandwiches toasted, go ahead and toast your bread.
Mix the mayonnaise, mustard, and balsamic together, then spread it thinly on one side of each slice of bread.
Place cheese on a mayo/mustard side of a piece of bread; if including proscuitto, place it on the provolone.
Spread the slices of avocado next, then the tomato, and season to taste with salt and pepper; then top with lettuce and the other slice of bread with the mayo/mustard side facing the lettuce.
Note: using a fully ripe avocado is very important.
