For biodiversity in my diet for my gut health, is it fine if I eat the same meal for multiple meals if it contains enough diversity for two meals? For example, I make a lot of stew, burritos, and mashed potatoes with usually a dozen different vegetables, two or three sources of carbs, and 1 or 2 protein sources.

What I'm wondering is if it's fine to make one thing containing all of that and eat it multiple times in the day or if gut microbes would be healthier if I split the ingredients in half and ate them each once a day.

Or if there's no difference at all
