Place all of the beets in a roasting pan and cover with water. Add a generous amount of salt and pepper, and drizzle liberally with olive oil. Cover the roasting pan with plastic wrap, and then cover tightly with foil.
Bake for 1 - 2 hours, depending on the size of your beets. Remove from the oven and let cool, then rub the skin off the beets with a paper towel. Slice into slices ½ inch thick.
Place the beet slices in a bowl and drizzle with olive oil.
Using a vegetable peeler, peel off strips of orange rind and add to the bowl with the beets and olive oil, then cut the orange in half and squeeze in a generous amount of orange juice. Salt and pepper to taste, and let the beets marinate in this mixture.
Heat a grill or grill pan to a high heat. Put the tangerine cut faced down and cook until it's nice and charred on the bottom.
On a plate, add a smear of hummus, then beats, and a tangerine half to squeeze over the beets. Top with basil.
