1Peel and cube the potatoes, then soak in water to remove excess starch.
2Cut the tomatoes and half of the white onion into chunks and blend until smooth; add 2 cups of water and blend again.
3Slice the jalapeno and the remaining half of the onion.
4Heat oil in a pan over medium-high heat, then add fideo, sliced jalapeno, sliced onion, and the cubed potatoes. Toast and fry briefly.
5In a separate pot, brown the ground beef. Season with garlic powder, cumin, chili powder, salt, and black pepper.
6Mix the toasted fideo mixture into the ground beef, then add the blended tomato sauce. Add more water to reach desired consistency, cover, and simmer.
7Add the canned beans, then cover and continue simmering.
8Roughly chop the calabacita and add to the pot.
9Cook until the calabacita is tender, then serve with optional pico de gallo and avocado.
