Possibly the Best Burger I Ever Made

It may not look like much, but this may be the best burger I ever made (and I have made a few). This baby was juicy and flavoursome. And very moorish. This is what I used:

Serves 8-10
2kg lamb mince
4 medium sized onions, chopped and fried
4 cloves of garlic
Peel and juice of 1 lemon
Peel of 1 orange
Handful of dried mint, crumbled into bits (fresh is probably just as good)
2 grated yellow beetroot
Chunk of swede, grated (approximately fist sized)
Salt
Pepper

Combine all ingredients in a large bowl, then form into 20-22 burgers. Place on oven trays and roast in oven for 20 minutes at 200 degrees C.

Enjoy with garlic butter and/or a wedge of blue cheese.
