Prick eggplant with a fork several times. Slice the top off the garlic head. Place both on a baking sheet (the garlic cut-side up) in a 400 degree oven for 40 minutes, until eggplant skin is very soft and the skin is wrinkled and cracked. Set aside to cool.
Heat oil in a large skillet. Add onions and cook 8 minutes. Add red pepper and cook 4-5 minutes more. Make a hole in the center of the pan and pour in cumin and coriander and toast 3-4 minutes. Stir in ginger, turmeric, and garam masala.
Meanwhile, cut eggplant in half lengthwise, and with a spoon, scrape the eggplant flesh out of the skin. Discard skin. Chop eggplant into bite-sized pieces. Squeeze garlic out of head and chop. Add to skillet along with tomatoes, chickpeas, and stock. Bring to a boil, then turn down and simmer 30 minutes covered, 10 minutes uncovered. Season with salt to taste.
Serve over rice.
