Pan-Frying Alternative: If you prefer not to deep fry, pan fry each vegetable separately: the potatoes in 2 tablespoons oil (about 10 minutes, until golden), the eggplant in 1 tablespoon oil (about 10 minutes, until soft) and the bell pepper in the oil left over from the eggplant (about 2 minutes, until lightly charred). Then proceed with Step 6.
