Heat oven to 375° F. Drain beets; set aside.
Season both sides of chicken with salt and pepper, to taste. In small bowl, combine 1 1/2 tablespoons mustard and 1 1/2 tablespoons marmalade. Brush mixture over chicken until completely coated. Bake chicken on rimmed baking sheet lined with aluminum foil about 20-25 minutes, or until juices run clear; set aside.
To make vinaigrette: In medium bowl, combine remaining mustard, remaining marmalade, chives, lemon zest and juice, 1/2 teaspoon salt and 1/2 teaspoon pepper. Slowly pour in oil while whisking vigorously until completely combined.
Slice cooled chicken into 1-inch pieces. Onto each skewer, thread one beet, one piece of chicken and 4-5 pieces of lettuce; repeat two times for each skewer, adding one beet at ends. Repeat to make eight skewers. Place skewers on large serving platter.
Stir vinaigrette; drizzle lightly over skewers. Sprinkle with almonds and cheese. Serve with remaining vinaigrette.
