Lentils are one of the top if not the top foods in antioxidants. But they are boring, yep not their fault but they are b-o-r-i-n-g. Still my bf eats whatever I make and sometimes that's lentil soup and sometimes he makes lentil soup (sometimes I add a small amount of lamb or beef, to the horror of vegans everywhere).

As for quinoa, avocado and feta I make this often, but when more stuff is in season. Tomatoes now are sorry winter tomatoes etc..
