As of 2012, if you have earned income of more than $1,010 per month at the time you apply, you are not eligible for SSI benefits. This figure is known as substantial gainful activity, which Social Security uses as evidence you are not disabled. The figure changes each year, and it was $1,000 in 2011. This is used only at the time you apply for SSI.
1 You can cut the partially-frozen steak with a large, sharp chef's knife, or you can use a commercial meat slicer for easy preparation and uniform thickness. 2  Most people won't have a meat slicer; a sharp knife will do just fine, even if it takes a bit longer.
I find skirt steak (aka flap meat) to be the most flavorful cut of beef there is. I make mine with a classic marinade of red wine vinegar, any good oil, some cumin and fresh ground black pepper and some fresh squeezed lime juice.
