How do you folks attempt to get 30+ different types of plant foods a week?

I’ve been listening to some interviews lately and a recurring theme is that the sweet spot for hitting a diverse microbiome is to consume 30 different types of plants per week. I currently eat a legume based soup for lunch every day that has 4-5 different types. But I normally eat the same soup every day for a week. Then normally one or two plants with dinner. Any good “hacks” to up those numbers?
