place shrimp in colander. Allow to thaw slightly then remove tails.
put cream, parmesan cheese, garlic and salt in crockpot.
add shrimp.
cook on low for about 4 hours. Less time is fine also. Enough to get the cream mixture cooked well together
On the stove top, boil several quarts of water. When water reaches boiling point add pasta and frozen vegetables. Cook till tender, but avoid mushiness since this may cook longer yet in the crockpot with the Alfredo mixture.
Strain in colander and add to crockpot. Give several good stirs. If it looks to dry and not creamy enough, add several more tablespoons of whipping cream. (Broth would also work).
continue to cook on low or set to warm till severing time. Enjoy!
