Making Salsa: Boil 3 tomatoes, 2 tomatillos, 3 serranos chile and blend with 2 garlic cloves, handful of cilantro. Set aside.
Making the Calabacitas Con Carne Molida: I browned/fried (with its own fat) 2 ls of 90/10 ground chuck with garlic salt, onion powder and pepper and a couple serrano chiles.
Then drain as much oil as possible and add salsa, and zucchini, 1 1/2 cups of water, 1 tbsp of chicken bouillon, and salt if needed.
Let it simmer on low for 10 minutes or until zucchini is done. Enjoy!
