Since our son was born a couple months ago, making food in bulk and freezing it has saved us from going out to dinner on a fairly regular basis. One of the big things is pasta sauce. Large batches of vodka, puttanesca and amatriciana sauce are fairly quick, and even bolognese isn't bad considering we use a food processor to chop the vegetables and most of the time is idle simmering time.
Still, I'm looking for more variety. Any recommendations for sauces that freeze well, particularly if they're "authentic" (or at least moderately so) that help make pasta a meal?
