The series is called "Quick From Scratch" and this recipe is in the chicken book. The series is good because the recipes are relatively easy to execute and the ingredients are accessible, but they feel a little upscale and all the ones I've tried are tasty.
So here's the recipe:
1 tbsp. Olive Oil
3 chicken breasts, cut in half
1 1/2 tsp. salt
1 onion chopped
4 cloves of garlic, minced
1 tbsp. fresh ginger, chopped
1/2 tsp. paprika
3/4 tsp. ground cumin
1/2 tsp. dried oregano
1/4 tsp. cayenne
1/4 tsp. ground turmeric
1 1/2 cups chicken broth
1 cup canned crushed tomatoes
1 cup canned garbanzo beans
1 zucchini, sliced
Season the chicken with a little salt and brown them in the olive oil. Add the onion and cook it until it's translucent. Add the spices, then everything else and simmer it for 15 minutes.
serve it over 4 cups of prepared couscous (a pasta from Morocco that is SO fast and easy to cook--follow the directions on the box) and sprinkle on some chopped parsley and some fresh lemon juice.
If you want to do it vegetarian, I think it would be great to add extra garbanzo beans, leave out the chicken, and use veggie broth instead of chicken.
To make the tostadas, you can either use premade shells that you'll find near the tortillas, or you can fry your own. Making your own is easy and they are so good when they're hot and crispy. Just fry corn tortillas one at a time in about one inch of hot oil. Keep them in the oil until they're crispy in the middle--when they're done, they'll pretty much stop bubbling.
Cook the pasta according to the direction on the package, and add the juice of 1/2 of a fresh lemon (I love adding lemon to chicken soup. Even if you use Campbell's, you should try the lemon). If you made your own broth, you'll have to add some salt to taste.
