Restaurants must have those temp. controls, in question is a lot of food and a lot of guests which must be served with specific food. Good tips by the way, i was wondering such a question for keeping meat warm.
Do some test, brake one egg and if it smells bad, it's not ok. Simple! That is the way how i check them if they sitting some time in the fridge, and yes im keeping them in fridge.
Nice Grilled Tilapia Taco. Easy dinner, i like it. Maybe i would add just a little bit of broccoli just for decor. But, that is only my personal thinking
Patrickamory, i agree with you about how is difficult to make beans like in pictures. There are a lot of side things that should do. I love black beans, your dinner looks wonderful!
