For the roasted beets: Place the beets in a sheet of foil and place another sheet on top and create a seal around the beet. Roast the beets on a baking sheet until tender, 45 minutes to 1 hour. Cool the beets in their foil packet for a few minutes, and then rub off the skins using a paring knife if needed. The beets need to still be a little warm to be able to remove the skins easily.
While the beets are roasting, toast the almonds in a small skillet over moderate heat, stirring occasionally, until golden brown. Remove and cool.
Slice the cooled and peeled beets into 1/4-inch thick slices and add half the vinaigrette, tossing to coat completely. Toss the remaining vinaigrette with the salad greens.
Arrange the dressed greens, and beets on a platter and top with the pear, toasted nuts, and goat cheese.
