I just made some last night with 5 medium sized tomatoes and it fed a family of four. I made raw sauce (uncooked) and it was awesome.
chop up some tomatoes - recipe calls for 6 regular sized
smash 4 or 5 cloves of garlic
1 tsp dried oregano
6 big leaves of basil chopped
1/4 cup olive oil
1 tsp salt
1tsp red pepper flakes
put in a bowl, mash up a bit and let sit most of the day so the flavors blend. When ready to serve pick out the garlic.
