Sainsburys feta, spinach, pea crustless quiche

I love sharp feta and juicy peas but this quiche wasn't as nice as I hoped.
Strangely sweet and lacked some umami and sharpness from the feta.
The description looks like feta is a main ingredient but ricotta is 7% when feta is 5%.

I feel that I have been scammed from the description and ingredients label.
