I love chunky garden vegetable pasta sauce, and after trying a few on Zaar I modified my favorite spaghetti sauce recipe recipe #22782, to have fresh tomatoes instead of canned, lots of fresh vegetables, and less fat from the meat. Easily hearty enough with vegetables to omit the sausage for vegetarians.
I find it easiest to prepare the ingredients first. Slice, dice, puree, open cans etc. For stronger garlic flavor, "crack" the garlic open about ten minutes before mincing to give the oils air exposure. Use whichever ingredients you love most. The more juicy your vegetables the less water you need as the sauce will thin as the vegetables cook. It's easier to start with thick sauce and thin in out than to try to thicken the sauce later.
My instructions may seem a little elementary for some more advanced cooks, but as I learned how to do many of these techniques while developing this sauce, I wanted to include them for more novice cooks. If you have any suggestions or corrections please let me know.
