Crock-Pot Vegan Marinara Sauce

This was really yummy.  I have made marinara sauce in the past, using both canned & fresh tomatoes.  I have to admit that using fresh tomatoes is a real pain, all the peeling & such.  I'm sure at some point (like when the garden is bursting with tomatoes at some point) I will make a marinara in the crock-pot from fresh tomatoes, but for now this one was really good & I was very happy with it.
