Authority at something

I am an authority at making and eating salads. Salads are so delicious and so easy to make. I have been making salads for many years. The ones I share on here are made by my sister, but I make salads too. Mine don’t look as good as my sister’s salads, that is why I share them. The ones I make are a little bit boring, but still yummy. I will share the salads that I make, sometime. But, the master at salad making goes to my sister. Like I said up there, I may be the authority of eating salads.
