I like tomato based vegetarian sauces (marinara, pomodoro, arribatta, vodka), or the olive oil & garlic, or pesto, or a mushroom sauce, but alfredo sauce is right out. The smell alone can turn my stomach. When we're having a special meal, one of my kids actually makes the sauce, but often we just use store-bought.
We're actually in the 3rd round of a jarred sauce taste-off. Prego, Classico, Berrtolli, Full Circle, Newman's, Rao's are in this round, some of them have 2 entries. The store shoppers must think I'm crazy with all the different varieties I put in my cart. It's a variety of marinara, tomato-basil, tomato-onion-garlic, but most of them are tomato-basil. We started with 16 and are at 8.
