I see no problem with a single drink at lunch, specially with your team. It helps you relax and build rapport imo.
At my previous job, my manager would take our 5-6 people team out for lunch and a beer for anyone's birthday and at the end of the year. I miss that.
My current job doesn't allow it, so going out for lunch with co workers is a little more stiff, and so is my relationship with my manager.
Last christmas I had to work during the break with only 1 co-worker, we snuck out and had pizza with a berr. It was great.
Caramelized Onions.
Not a topping, but underrated: ricotta instead of tomato sauce. So good!
