I'm not entirely sure what the OP for this recipe was on, but it wasn't doing things right proportionally. It should be noted that I did make the meat filling using the recipe for the Taco Bell clone beef recipe (see profile as I made it at the same time as this). The filling total when proportioned out to what it was listed as didn't wrap up AND blew out (see second pic). When portioned out to not cause this is more like 1/6 of the filling. I do not expect the tostada used to remain crunchy when I defrost and reheat these.
Use less sauce since the water from the veggies make it saucy. Only used a little more than half the mixture since my pan wasn't tall enough to add the third layer. The second layer after the noodles was the veggie mixture, sauce and cheese.
The food processing was annoying but made everything nice and uniform.
