Instructions

Preheat oven to 400°F.
Place the tortillas on a baking sheet and brush them with oil on both sides. Bake 4-5 minutes on each side until crispy. Remove from oven.
Meanwhile, heat the oil in a large skillet over medium heat. Add the onion and garlic and sauté until slightly softened 4-5 minutes. Stir in the tomatoes, chili powder and cumin and cook another 2-3 minutes. Add the tuna and stir gently to combine, trying not to break it up too much. Season with salt and pepper. Remove from heat.
Mash the avocado, lime juice, cilantro and salt together in a bowl.
To assemble the tostadas, spread each tortilla with some smashed avocado and top with some of the tuna. Then, top with your favorite toppings like sour cream, salsa, cilantro, and coleslaw mix. Serve lime wedges on the side.

Notes

I like to make my own tostadas by baking corn tortillas in the oven until crispy. However, to save time, you can always buy tostadas from the grocery store.

Although tuna is the star of this dish, you can easily substitute other proteins like chicken, steak or shrimp. To make this dish vegetarian, you can use roasted vegetables like bell peppers, mushrooms, onions or corn.

I like to top my tostadas with creamy avocado because avocados are so nutritious and creamy; however, you can also used mashed black beans or refried beans (which are traditional).
