Cut 10 oz. of grape tomatoes into halves and place them in a medium mixing bowl. Now, slice 1 cucumber into thin slices on top of the tomato halves. Next, use kitchen shears to snip the green ends from 1 bunch of green onions on top of the tomatoes and cucumbers. Drizzle 8 oz. Italian salad dressing over the top and blend all of the ingredients gently with a large spoon. Finally, remove the prepared relish to a serving bowl (clear, if possible). Cover with plastic wrap and let stand 8 hours or overnight. You might want to stir this occasionally, or place it in a covered container, which you can shake occasionally to distribute the flavors. This is a gorgeous, tasty relish that will be eye-catching at your lunch or dinner!
