In a small saute pan add 2 tablespoons whole butter, dash of cayenne, 3 tablespoons sugar, 1/2 teaspoon salt, and the 1/2 cup of pecans. Cook this slowly over a very low flame, taking care to stir carefully and occasionally. The sugar will burn easily if the flame is too hot. On a stable cutting board, julienne the red pepper and then peel and section the 2 oranges. Squeeze the remaining orange pulp over a large bowl and to this add the 1 tablespoon of olive oil. Toss the salad greens in this and then place on a salad plate. Arrange the oranges and red bell pepper slices on the top and garnish with the caramelized pecan halves. Allow the pecans to cool before eating.
