What i did was get a mixture of vegetables baked them after spraying with oil, the vegetables i used this time was
Once the vegetables where cooked in the oven i blended them down adding some herbs and parmesan cheese, most of the items i used had been already in my house
Next i made my meatballs, and well im not really that big on the taste of meat either, years ago i learnt a trick which made the Meatballs really yummy and moist.
I use a can of baked beans
Sure it may sound really funny but once to blend them down they turn into a paste and in the meatballs i dont think you can really work out what the taste is.
Next i baked the meatballs and mixed them with the pasta and sauce i had made.
Turned out pretty good i think
