Hi, so since almost 4 years I start the paleo diet and it's great. I saw a lot of good results on my body but especially on my energy and fatigue! But with a new diet you have to change your lifestyle, your grocery list and start to cook a lot more, but lucky me, my grandparents, my parents, my uncles own their own restaurant so I was raise in a italian culinary world.
So here for you one of my favorite recipe, is really really simple.
1-Buy a Cassava in every grocery, specially the poorest one :D

2-Peel the Cassava (tapioca) with a peeler and boil some water
3-make them boil between 20 to 25 minutes, make them tender, especially in the middle
4-put them in a food processor with some salt and butter(1) or olive oil! Not too much (depends how much italian you are)

5-What kind of sorcery is this!!! Yup this is what happened(2)
6-Take a rolling pin to spread it on a wax paper
7-precook a little bit before you put the topping on it
8-do what you want with it, pizza, tortilla, focaccia, burrito
1-Butter is good for you
2-Sometime, the cassava will stick all over the food processor, just put some tapioca flour to fix everything!!! good luck!!
