Put the meat in a large to medium skillet over medium to high heat. Start to break up the meat as soon as it's in the pan. When it starts to sizzle, sprinkle the seasoning evenly over the meat and keep using a sturdy spatula or meat turner to mix in the seasoning and break up the meat. Stir and break-up the meat every minute or so until it's browned. Meanwhile - put all the ingredients, except the tortillas out in bowls if you want folks to make their own (my standard style). Or, set the ingredients out on the counter if you plan to build the tacos. When the meat is a few minutes away from being finished, warm the tortillas. I put them in the toaster oven at 160 degrees F, in layers separated by parchment paper or tinfoil (you can stack them without it, but sometimes the tortillas will stick to each other). I warm them 3-5 mins, until they are just warm and pliable. You can also warm them in the microwave, separating each with a paper towel and warming the whole pile for 20-30 secs. When the meat is browned, assemble the tacos by putting a few tablespoons of meat down the center of a tortilla, then layer the other ingredients as desired. I usually put the cheese on right after the meat so it gets a little melted, but my husband prefers it on top.
