You're perspective is skewed. Your knowledge only includes the local plants that we have created into our international rummaging choices. Bell Peppers are just one modern variety out from the ~30 species of chilies we've discovered. Same for carrots and potatoes and lettuce. I look at the variety of edible vegetation I can get at the grocery store and the only thing I really think of is it's a good day that I don't have to walk 20 miles to the fruit trees to pick the fruit before all the animals do.

Meat? tons of variety, there are like twenty different cat to dog sized animal species in my Montana wilderness before I even have to get to the large herbivores that have less variety. And meat is special anyways, the mink or weasel you can kill is chock-full of 2-5 years worth of collecting resources from various animal and vegetable sources.
