In a blender or food processor, mix the basil, mint, 1/4 cup of broth, green onions, garlic, 1 tablespoon chopped ginger and lemon. Blend until minced.
Cut the chicken into bite-sized pieces and combine with the soy sauce. Let it briefly marinate.
Chop the onion, chiles, eggplant or other vegetables being used.
In a large pan over high heat, add the sesame seed oil. Once the pan is very hot, add the vegetables and cook until tender, 4-8 minutes. Remove to a bowl.
Add another tablespoon of sesame seed oil and add the basil-lemon-ginger-mint mixture and cook for 1 minute, stirring.
Add the chicken, marinade and 1 tablespoon finely chopped ginger to the pan and cook until done, 2-3 minutes.
Add the 1/2 cup of stock, bring to a boil, and re-add the vegetables to the pan. Cook for another 1-3 minutes. Serve with rice or noodles.
