These are some tostadas I made with ground beef
First I smother sour cream on the tostadas
Here they are with ground beef and cotija cheese
Then I top them with some cabbage mix
For the cabbage I basically get a bowl and pour some white vinegar, chop some onion and jalapeño or serrano and squeeze some lemon juice and let it sit a bit to flavor the vinegar.
Then I shred some cabbage and toss in some tomato, salt pepper and oregano and mix it all around and put it on the tostadas.
Then if we have some avocados we toss some on top and pour valentina or tapatio
