Input: [header] How to make taco salad [title] Mix the salsa and sour cream together in a small bowl using a fork or mini whisk, then set it aside. [step] Keep mixing until the color is uniform and there are no unmixed streaks. Set the dressing aside, preferably in the fridge, so that it's nice and cold. <sep> (A) [substeps] Make sure that you are using the smooth kind of salsa and not the chunky kind; do not use pico de gallo. [title] Cook the ground sirloin over medium-high heat. (B) [substeps] If you can't stand it, skip this step and prepare your dressing for enchiladas, mac' n' cheese, or any other dish. [title] Mix the cheese and corn starch into the dressing. (C) [title] Place the taco dip halves to side, since they will be facing up again. [step] Then, place the brisket, olives, tahini and onion wedges halves to the same bowl with the salsa mix. (D) [title] Heat oil in a skillet over medium heat, then cook the diced guacamole on high for 6 minutes. [step] The stickiness of the guacamole helps the flavors stay attached, so don't let it get too sticky.
Output:
A
