Growing protein

I'm growing quinoa this year in among some squash plants. Might be a mistake if they grow too big and bushy. I grew about 12 plants a few years ago and got about 2kg of grain off them. I didn't find it too hard to clean the grain as could listen to music or the radio. Creatures are not supposed to like them but something had started nibbling them before I harvested them.
I also grow french beans for drying, a climbing one Soisson, 2kg from a 13' row last year but hoping to do better this year. I grow a dwarf one as well but no idea of variety, it was a packet of beans I brought back from France about 10years ago now. Laast year it was decimated by slugs but this year is doing well so far. I also grow peas generally for freezing but this year I've had a bumper crop and stopped picking after I had 9kg in the freezer. So it looks like I'll have a few kg of dried peas as well.
Last year I got a lot of hazel nuts but it is a hit and miss crop with the squirrels - mind you most crops can be affected by some pest/disease.
I couldn't grow sunflowers for their seed here as birds start eating them before they are fully ripe. I've grown Lady Godiva pumpkins in the past for their seeds but we didn't eat them all and the flesh is not really edible.
