For my son's upcoming birthday party, he wants to serve a spaghetti dinner with salad and bread. We are expecting 25-30 family members and I don't know how to make this much ahead. Can I make the sauce ahead and re-heat it in a crock pot? Will it burn that way? Is there any way to make the pasta ahead? I only have 4 burners so can I boil 4 pots of pasta at once or is that crazy? Any ideas are appreciated.
