1. Pierce potatoes all over with a fork. Place in the microwave and cook at 50% power until potatoes are tender (20-25 minutes). Stop every 5 minutes to rotate potatoes and check for doneness.
2. While the potatoes are cooking, pour boiling water over sun-dried tomatoes in a small bowl. Let soak until soft (5-10 minutes). Drain and slice.
3. Combine the tomatoes, basil, capers, garlic, and oil in a small bowl. Season with salt and pepper. Serve over the baked potatoes.
