Puree tomatoes Pour in sauce pan. Slice onion in half, put in with tomatoe puree. Throw in margarine (Olive oil may be substituted, but it doesn't mix as well). Add salt and vegan sugar and other spices to taste. Simmer for 45 minutes. Remove onion halves, and spoon liberally over pasta, (preferably done al dente).
Note: This sauce may have a tendency to come out somewhat thin compared to what we Americans are used to, but its more autentico than Ragu.
