Marinate the shrimp in the vinaigrette for 20 minutes or so. Drain the shrimp, retaining the marinade. In a large skillet over medium heat, cook shrimp until pink, about 3 minutes. Remove shrimp from skillet and keep warm. Place marinade, cream cheese and half of the basil in the skillet. Cook and stir until well blended; return shrimp to pan and continue cooking until heated thoroughly, stirring occasionally.
To serve, place a mount of noodles on plate; top with shrimp and sauce mixture. Sprinkle with remaining basil and the shredded parmesan cheese.
You can also add fresh chopped tomatoes for extra flavor, color and texture.
I only bought the shrimp and basil to make this meal; all other ingredients came from my pantry and fridge. Half a pound of shrimp cost $3.00, and the portion of basil I used about $0.50. The pasta was free, using coupons at a Harris Teeter doubling event, and I paid less that $1.00 for the entire package of cream cheese, making the portion I used about $0.25. Making my own vinaigrette cost pennies, as did shredding the Parmesan from a block. I would estimate the cost of this main dish to be around $4.00 0r less. The additional side dishes and bread would bring the total to somewhere between $5.00 or $6.00. Not bad for an elegant anniversary dinner!
