Ditrections:
Season the sliced beef with one teaspoon each of salt, pepper, garlic powder, cumin and oregano. Stir well to combine. Set aside. Preheat 3 tablespoons of oil in a large pot at medium heat for 3-4 minutes. When ready, brown the beef in the preheated oil, stirring as needed for 10 minutes.
In the blender, combine the tomatoes, 1/2 of the onion, garlic, 1 serrano, cilantro, tomato sauce(if using) and 3 cups of water (or broth). Season with salt and pepper to taste and blend on high until smooth.
To the beef, add the remaining diced onion and poblano pepper. Saute for 5 minutes. Add the reserved whole serrano pepper. Add in the sauce from blender. Bring to a boil, reduce heat and continue cooking(mostly covered) for a good 15-20 minutes or until sauce reduces and becomes darker. Fold in the potatoes, cover and continue cooking until potatoes are cooked through, about another 15-20 minutes. You can adjust the spices to your liking as the beef cooks down.
Serve with a side of rice, beans and warm tortillas. The beef can be substituted with pork steaks or boneless chicken thighs, sliced. Add in your favorite vegetables like zucchini, chayote, carrots…
Enjoy !!
