Cut the avocados in half, remove the pits, and scoop out the flesh with a spoon. Combine with the lemon juice and salt in a bowl and mash. Add the green onions, and, if desired, tomatoes. Press in the garlic. Chill in the freezer for 10 minutes. Mound the greens on 2 large or 4 small salad plates, and top each with guacamole.
