I'm lactose intolerant and I miss milk greatly. It doesn't help that I also have a mild reaction to nuts, so almond milk is out.

Oatmilk is just meh.

Best I've found for cheese substitute so far is a brand called follow your heart from Sprouts. It is only good if really well melted on toast, otherwise it's very much unsavory. Stay away from the mild cheddar and Gouda, both are really bad. The provolone is ok, the American is ok as well.
