Bring about 2 quarts of water to a boil and add 1 tablespoon salt. Add the pasta and cook until just tender--about 11 minutes (check your box).
Meanwhile:
In a non stick pan, cook the bacon until crisp. Remove from the pan with a slotted spoon and place on paper towels to drain.
Remove all the grease from the pan but 2 tablespoons.
Add the garlic and the tomatoes and sauté until just softened, about 2 minutes.
When the pasta is cooked, transfer it to the tomatoes and garlic, add the bacon back in and add the arugula or lettuce of your choice. Sprinkle on the salt, pepper, parmesan and the pasta water and toss to combine. Serve warm or room temperature, but not cold.
