Start by boiling water in a large pot. Once the water comes to a rolling boil, add 8 oz of spaghetti noodles.
While the pasta is boiling, dice your cucumber and tomatoes into roughly 1/2" size pieces. You will want approx 2 cups of each.
Cook spaghetti noodles until they are al dente which means they are cooked about 90% of the way and are still slightly firm. This will help prevent them from getting mushy in the salad.
Drain pasta in a colander in the sink and rinse with cold water. This will cool the pasta down and stop the spaghetti from cooking any further.
Combine the cooked spaghetti, tomatoes and cucumber in a large bowl and stir.
In a small bowl, combine half the packet of Italian dressing mix with 1/8 c of vinegar, 1/4 c of olive oil and 1 1/2 T of water. Use a small whisk or a fork and stir until its combined. Set the remaining half of the seasoning packet aside.
Pour the homemade Italian dressing mixture over top of the pasta mixture and sprinkle 1/2 t of salt. Toss to combine.
Cover bowl with plastic wrap or tin foil and place in refrigerator. Chill for 1 hour.
Once chilled, remove bowl refrigerator and give it a good toss. Sprinkle the rest of the Italian seasoning packet into the salad. Give everything one last good stir and serve.
