i saute onions and garlic in olive oil, then add veggies such as:
or whatever else i have around
then i add chopped tomatoes until it reaches about 2/3 of the way up the pot.
i add a spoonful of honey or molasses, and salt, pepper, oregano, parsley, and whatever other herbs/spices to taste
i let it cook down to desired thickness, then can.
i have a very eaasy canning method:
boil jars in a big pot.
keep them in a 250 degree oven while preparing the sauce.
take jars out of the oven 2 or 3 at a time.
add a spoon of salt, and a slosh of lemon juice to each jar.
fill jars to within 1/2 inch of top with tomato sauce (sauce must be boiling hot)
put the lid on, and tighten screw cap
turn jar upside down.
start next batch.
when all of the jars have cooled, i turn them rightside up and make sure they have sealed properly.
if not, i pour the sauce back in the pot, resterilize the jar, and start again with a new lid.
it is so easy, and i have had the sauce last at least 6 months on the shelf.
