Oven baked tostadas are one of my favorite weeknight meals. Not only are they simple to make, they are so versatile as well. Once you get the base down (tortilla, beans, cheese) you can top it with whatever you want! Personally, I like shredded chicken, salsa, diced red onion, spinach, sour cream and fresh jalapenos, but you can top them with whatever your preference is. I also opt to bake corn tortillas instead of buying already made tostadas or deep frying them in oil to make this dish lighter.
