easy, creamy, homemade spaghetti sauce

tonight the husband came home with a couple of sweet yellow tomatoes a customer had given him at work.  i had never before had a yellow tomato and let me tell you--delish!  they are very juicy and sweeter than a red tomato.  i decided to make some homemade spaghetti sauce and it turned out amazingly! 

i used:

2 medium yellow tomatoes (diced)
2 medium red tomatoes (diced)
1/2 yellow onion diced
1/2 green bell pepper diced

i chopped all the fresh ingredients and put in medium size bowl.  this is where it gets a little messy.  with clean hands squeeze tomatoes until you get a nice salsa-like consistency.  then add herbs/spices.  i did not have any fresh herbs on hand so i used dried. 

i added:

basil
oregano
onion powder
garlic salt
chili powder
sugar
worcestershire sauce
parmesan cheese
1 can tomato sauce

my husband thinks it is a crime to have meatless spaghetti so i browned some ground beef and added sauce mixture to the cooked beef.  i think the sauce would be amazing without the meat though.  after sauce had cooked for a while i reduced the heat to a simmer and added some heavy cream.  i did not measure anything but i would guess i added about 1/4 cup.  my sauce was a little runny so i added a pinch of flour to thicken things up.  before serving and after removing sauce from the stove i stirred in a handful of grated mozzarella cheese. 

i will now be searching for these yellow tomatoes because they were heavenly.  we both gave this sauce 2 thumbs up--don't think we'll ever be going back to canned.
