Was the ham cooked over night or left in the oven. If the ham was left in the oven with out any way of keeping it out of the temperature danger zone then it needs to be thrown away. It most likely has serious bacteria growth which can make you very ill.
Technically, you can eat collard greens with ham and bacon if left out overnight, but I wouldn't recommend it unless you're feeling lucky or have a strong stomach. Bacteria can multiply quickly at room temperature, so you might end up with a one-way ticket to the porcelain throne. It's better to play it safe and toss those greens in the trash.
It is not safe to eat cooked venison that has been left out at room temperature for an extended period, such as all night. Bacteria can grow rapidly on food left out for more than two hours, increasing the risk of foodborne illness. It's best to discard the venison to avoid potential health risks. Always refrigerate leftovers promptly to ensure safety.
Enchiladas should not be left out at room temperature for more than 2 hours. Using 1 hour as a limit is even better.

It might not be 'spoiled', but I would not recommend using it. Cooked veggies left out that long could have grown microbes & toxins that could make someone ill. The presence of pathogens & their toxins is not obvious. Do not use it.
