Prepare an ice bath in a large bowl and set aside.
Bring a small pot of very salted water to a boil. Add the asparagus and cook for 1 minute when the water is boiling.

Add cooled pasta, red onion, peas, cherry tomatoes, cottage cheese sauce, and remaining salt to a serving bowl and toss. Add the fresh dill and basil, and toss again.
Strain the asparagus and toss it into the salad.
Heat olive oil in the saucepan and add the garlic to the pan. Saute for 1-3 minutes or until golden. Remove from the heat and pour over the pasta salad and toss.
