Can't help you with measurements as I don't really do them.
But you won't go wrong by sauteing some onions in a pan with oo or bacon fat, adding some dried Italian herbs, salt, crushed red pepper flakes, garlic, and some anchovies. De-glaze with red vino, then add your canned sauce to that.
The canned tomatoes can be roasted in the oven. Prep them with some oo, salt, garlic, herbs, etc. Once caramelized, take out of the oven, de-glaze roasting pan/tray with red vino, then add to your simmering sauce.
A good way to build some depth of flavor.
