Have you ever put a beef meat for a mixed veges in a coconut milk recipe? How was it?

It was my first time to put a beef of a mixed vegetables in a coconut milk menu. Never in my life had I seen one with it, but out of curiosity and am craving of beef meat that time, I put it as a mix of such. For sure, it won't poison me because the beef and all of my ingredients are fresh. Then I began my kitchen journey for such menu. Yes, I put several ingredients of vegetables like leafy yum leaves, swamp cabbage/ kangkong, eggplant, string beans, taro root and squash along with the fresh spices like lemon grass, ginger, bell peppers of two different color, then a dash of salt and beef bouillon. Hoorah! I love the taste of it with beef! Well, for that time when it is still warm. Then since I cooked more than I one sitting of eating I  have the leftover to which I actually intent to stash for future meal(s) just a typical way when I cook such menu. But to my surprise, the time that I wanted to eat already, the food was not good anymore. It bubbled. It was not that I did not put it in the refrigerator directly because I did, I even put some in the freezer. And I thought of, because it is beef. Beef bubbles. I don't know but it will be a long time and have to persuade myself strongly with a strong proof that beef, is good to mixed vegetables in a coconut milk, that is hard to do. However, am not closing my mind for any experienced cook or chef about this. For now, I still cannot comprehend of mixing beef of such recipe. I promise myself of putting not. Really, it is a waste of ingredients thinking that such are not cheap. :-( Lesson learned for me.
