I've never made my own spaghetti sauce. I always thought it would be too much work. But this recipe looks so easy and I love that I can use my crockpot for it. I'm going to give it a go. Thank you!

This Slow cooker hearty spaghetti sauce sure does look hearty with all those yummy chunks of tomatoes and veggies in it. I bet it would be great over penne pasta or another chunky-style pasta. I will have to give this a try sometime in the near future when we have pasta. Looks great.
