No, you wouldn't put a comma after spagehetti. What you are saying here is I love this and that.
This=spaghetti That= meatballs. Two things.
I love my cat and dog.
I love to walk to school and to ride my bike.
If there were three things, then you would need a comma.
I love my mom's spaghetti, turkey meatballs and sauce. (Three things)
So, I disagree with Phillip. I'm not sure what he means when he says the information is "explanatory". This would only be true if you were providing more specific information about the spaghetti. For example:
I love my mom's spaghetti, the one one the table, and the turkey meatballs. Here you are telling a bit more information about which spaghetti you are talking about. Perhaps there are lots of different plates of spaghetti on a buffet or something.
So, no comma in the example you gave. Leah G.
