Both are true:
• there are foods outside meat/veg
• there are lots of great ways to prepare meat/veg
There are enough paleo cookbooks and websites to occupy a person until the heat death of the universe so it seems a little daffy to equate the removal of refined ingredients with monotony. I try to picture a medieval king's dinner table and eat like that.
I eat starch every day though it's chosen carefully (mashed plantains with cinnamon, etc.) and may be unfamiliar to someone accustomed to bread and pasta. I eat 1-2 fruit servings per day, mostly as a palate pleaser. I wouldn't try to fill up on it. When I eat nuts I count out 5-10 of them and generally avoid the commercially oil-roasted kinds. Nut flour and nut butter are social/seasonal treats.
I eat starch pretty much every day.
There's a lot of variety to meats and vegetables and even a lot of variety to starches. What isn't a lot of variety is when you realize that all your food is mostly bread, cheese, Tomatoes. Or corn, wheat and soy.

A lady friend of mine makes great fried plantains. Its not the plantains though its the garlic dip she makes. I believe its olive oil, lemon juice and mashed garlic mixed. Dip some salted, coconut fried plantains in that, yum.
I eat whatever the hell I want. 85% of the time that's primal in the form of meat/fat/veggies (including rice and potatoes). People get so wrapped up in the dogma they fail to realize that making better decisions is more important than making the perfect decision. When people first convert, they feel any deviation from what grok did translates to failure. Life's too fuckin' short. Eat whole foods, avoid processed grains and refined oils. That's it.

Whether you use factory or grass-fed/wild, organic or conventional produce, even if it were true that all we eat are meat and veggies, there are tons of meat and veggie combinations:
Animals (as in anything not a vegetable) just off the top of my head that are available in all but the smallest of towns:
Liver - even in smaller areas, chicken and beef liver are usually available.
Using any of those as a main dish paired with so many veggies available that no off the top of my head list could even make a dent, the combinations are many. Add a little rice/potato/sweet potato once in awhile to stretch a more expensive cut. Make stews and hearty soups. Casseroles. Experiment with some spices. Curries are pretty easy to make as are stir fries. Learn about squashes and roots.
If you want to splurge occasionally on things not sold locally, almost anything can be found online. It might be expensive, but realize that folks aren't lining up around the block for kangaroo tail (at least not in the U.S.).
So, beyond meat and veggies are meat and veggies - combined in ways that make them interesting. Play with your food!

There are also many obscure meats/vegis depending on your location if you get really bored. Octopus, liver, chicken feet, bone marrow, pigs feet, snails, bugs, duck tongue, duck head, duck hearts, pigeon, jelly fish, intestine, stomach, honey bees, sea worms, pig tail, ox tail, ox penis, fertilized duck egg, snake, monkey brain, donkey, dog...just to name some of the meat items.
