wintertime tomato sauce

Makes about 4 cups

One 28-oz can whole peeled tomatoes 
½ cup red or yellow onion, finely chopped 
2 oz olive oil 
2 TBL unsalted butter 
½ tsp sea salt
2-3 sprigs fresh oregano, winter savory, or thyme, or a mix thereof; alternatively, ½ tsp dried oregano or dried rosemary

If there are any basil leaves in the tomatoes, remove them. Puree tomatoes with juice, leaving a little coarse. Simmer chopped onion in olive oil for 3 or 4 minutes until soft with a little color.
