A flavorful and spicy Mexican-inspired dish perfect for a quick and satisfying meal.
Slice the onion thinly and sauté in a skillet with a bit of oil until soft and translucent.
Cook the onions on medium heat to avoid browning and achieve a sweet flavor.
Blend the tomatoes, chipotle chiles, garlic, bouillon cube, and salt until smooth.
Adjust the number of chipotle chiles based on your spice preference.
Pour the blended sauce into the skillet with the onions and simmer for 5 minutes.
Stir occasionally to prevent the sauce from sticking to the skillet.
Spread sour cream on each tostada, then top with the chipotle chicken mixture.
Warm the tostadas slightly for a better texture.
Garnish with shredded lettuce and a sprinkle of parmesan cheese.
Serve immediately to keep the tostadas crispy.
