I can for foliage and flowers but not produce. It doesn’t fit with prime directives (stuff that looks nice all year round/ stuff it doesn’t matter if the kids trash); I never end up with a “bumper crop” and at the time that eg: tomatoes are super cheap in the shops, I end up with 3-4 leathery, watery tomatoes no-one wants to eat.
Growing vegetables is hard work. Farmers are skilled and knowledgeable!
Peas, and beans 
Trombocino 
Beans later
My biggest success is pea sprouts from Vertical Veg (this is an inspiring site). And we grew a sample and sold peas in packets at the Summer Fair, which the kids love.
I grow beans every year because I like the way they look but we rarely eat them as usually only about three of them are ripe at time. These last 2 years, I have grown them on the balcony up a clothes rack.
And I grew trombocino which looked AWESOME but didn’t really make it as a dinner. In 2021 I am going to try to grow herbs and leave it at that.
