Preheat oven to 350 degrees. In a 13x9" glass baking pan, pour
1/3 of the spaghetti sauce. Sprinkle chicken tenders with garlic
salt. Place chicken tenders into each manicotti noodle, using
more than one to fill each shell if needed. Place in baking dish.
Pour water into remaining spaghetti sauce in jar, close jar and
shake well. Pour this mixture over filled manicotti shells in
baking dish, making sure to cover pasta completely. Cover with
mozzarella cheese. Cover tightly with foil and bake at 350
degrees for 80-90 minutes until pasta is tender when pierced with
a fork.
