Bring a pot of salted water to a boil and cook your pasta according to the package instructions. Drain and set aside to cool off.
In a large bowl, add the romaine, artichoke, bell pepper, corn, scallions, cheese, and cooled pasta.
In a jar with a lid, add the lemon, oil, mustard, soy sauce, and salt and shake vigorously to combine. Pour over the pasta salad and toss to coat. Taste and add more salt, lemon, or oil, if needed.
Serve topped with a sprinkling of cheese and some black pepper.
