I ate less than a Kezayis bread by a meal

I sat down to eat a regular meal and washed for bread. By the end of the meal I did not have a kezayis bread.
During the meal I had various foods, mezonis, wine and grapes and fish and meat.
The fact that I am apparently not mechoo’yiv in Birchas hamozoin, what am I supposed to do?


You should eat more bread so your bracha on the washing isn’t a bracha levatalla
