Waiter there's something in my... sauce!

This month's Waiter there's something in my.. event is dedicated to sauce! I found out I'm really late, but apparently they're still waiting for entries... yeeeh!
So, I'm posting the recipe for a Mexican mole, which we made a few nights ago at a Mexican dinner we cooked at my place. It's a really special one: 'Pipian Verde' / 'Pumpkin Seed Sauce'!
To make it, you have to boil 12 chiles serranos in water, for 8 minutes, then add 1 kg of tomates verdes (green tomatoes), husks removed, and boil for ~5 more minutes. Drain, remove the stem from the peppers, if there were some, and blend in a blender. Add 1/4 of onion, 2 cloves of garlic, 1 cup of cilantro, 1 leaf of lettuce (I didn't add this), and blend altogether.
Then, heat 2 tbsp olive oil in a pan, add 1 1/2 cups pumpkin seeds, and toast for a few minutes. Grind in a blender or nut grinder, then add 1/4 cup unsalted peanuts and blend together.
Heat up 2 tbsp olive oil in a pan, add the grounded nuts and cook for ~2 minutes. Add the blended tomates verdes stirring constantly. At this point, add a chicken bouillon and 1 cup water (or 1 cup chicken stock) and simmer uncovered for ~10 minutes. It's ready! (recipe from 'Mexico, The beautiful cookbook')
This mole is usually served with chicken. So, we had also boiled 3 chicken breasts with 1/4 onion, 3 cloves garlic and 3 springs of parseley for 20 minutes, and then simmered the chicken breasts in the sauce for another 15 minutes:
But we had a huge amount of mole for the chicken we made.. and it's so good: creamy, nutty and spicy at the same time! My Mexican friend who cooked with us suggested to use it later with white rice, or with fish, or just breaking some eggs and cooking them in it.. I'm looking forward to trying some of these suggestions!

Thanks Andrew for organizing this round of 'Waiter, there's something in my..' - looking forward to the roundup!
