I canning tomatoes that my husband loves to take for lunch. It is very simple and goes with lots of lunches.

I just chop up large tomatoes or leave small ones whole.

Then I mix some olive oil, salt, pepper, sometimes some garlic or basil to taste.

I put a little fruit fresh to keep color.

Then I put them into jars (jelly jars) and process in boiling water bath for 20 minutes.

It's very easy to grab for lunch.
