How to Make Harissa Shakshuka Less Spicy

I know shakshuka was trendy a couple years back but this is the first time I’ve come around to actually making it at home. Using the harissa you guys sell villa jerada I was blown away by how good it turned it. I even slightly over cooked eggs and it was so tasty. Now the real problem I loved it so much I could easily make this 2-3 times a week but my family is from Central Europe (Czech) and they do not like spicy foods. I guess I will be cooking 2 meals at once unless I can figure out a way to cool down the heat for their portion after it’s all prepared.
