Posting this here for future reference & to share with friends. It actually came out pretty good.
1 lb box of noodles (I used shells because that's what I had on hand. DO NOT PRE-COOK!)
1 qt jar of marinara pasta sauce (Rinse jar out with a 1/4 water, approx. and pour remnants in.)
1 qt jar of salsa (See above.)
1/2 lb shredded cheddar cheese
sour cream (to taste)
In an 11 x 7 x 2 in pan, pour pasta sauce and salsa. Mix together. Add box of noodles, stir together until noodles are coated. Top with shredded cheese. Bake at 350 deg F. for 1 hour. When serving, add a dollop of sour cream.
