Dressing - mix all the ingredients and set to the side until the pasta and asparagus are cooked.
Salad - In a large pot of salted water, boil the pasta according to directions. Approximately 3 minutes before the pasta is done, add the asparagus until is comes out al dente. Now drain the pasta and asparagus. Rinse under cold water for just a few seconds to stop the cooking process and cool slightly.
Combine - Now toss the still slightly warm pasta with the dressing. Add in the scallions, extra salt and pepper and serve garnished with the cheese fresh lemon slices. A nice simple salad!
Now this is a very light tasting salad with a very simple dressing. It doesn't have bold flavors, but subtle flavors which is a nice compliment to a fresh herb roasted chicken breast or piece of fish. This is all about fresh subtle flavors.
