Pasta plays a supporting role in this filling Mediterranean salad, while canned artichoke hearts, feta, and white beans share the spotlight.
In a large saucepan of boiling salted water, cook pasta until 1 minute short of al dente. Add sun-dried tomatoes, and cook until tender and pasta is al dente, 1 minute more. Drain pasta and tomatoes, rinse under cold water, and drain again; transfer to a large bowl.
Make dressing: In a large bowl, whisk together vinegar, oil, mustard, and 1 tablespoon water; season with salt and pepper.
Add pasta and tomatoes, romaine, beans, artichoke hearts, and feta; toss until combined, and serve immediately.
To soften sun-dried tomato strips, toss them into the pasta pot at the last minute.
