This sauce is great. I used diced tomatoes and then added dried basil and oregano. 1 bay leaf also. I omitted the salt and pepper. It was very easy to do. Thanks Dreamer :) Made for Holiday tag

PERFECT! This speghetti sauce is a perfect combination of saucy texture with nutritious veggies easily hidden! ;) I made exactly as is except I left out the mushrooms (DD won't touch anything with mushrooms). I've been looking for the perfect speghetti sauce and I think I've finally found it! I love how it can cook in the slow cooker and I can freeze some for later. I put everything in the crock pot at 8am, cooked it on high, and it was ready by noon. Thank You!!! Made for veg*n swap.

Thank you for sharing this recipe! I've made huge batches of it to freeze several times now. The food processor makes it a simple process. My fella thought the carrots were weird, so now I shred them instead of chop, so we get the flavor without the noticeable chunks.<br/><br/>I've been experimenting with adding Italian sausage seasonings (garlic, red pepper flakes, fennel seed, etc), which is really good, too.<br/><br/>I shared your recipe on my blog:<br/><br/>Thanks again!
