Place in a heavy-duty zip-top plastic bag; seal. Let stand 15 minutes. Peel; cut into 1/2-inch pieces. Add bell peppers and pine nuts to eggplant in bowl; toss well.
Heat oil in a nonstick skillet over medium-high heat. Add red pepper and garlic, and sauté 30 seconds. Add vinegar, capers, sugar, and salt. Bring to a boil; cook 30 seconds. Pour over eggplant mixture; toss. Marinate at room temperature for 2 hours.
