<prompt> Human: The vertical diet is a diet that has a large focus on red meat steakbeef and rice. How can I find a cheap way to get stuff such as Lamb, or beef? The stuff at the supermarket cost about 3.33lb on sale but I would like to find an option that costs less.  <response>: Find a Mexican Carnecería. When I was in college sports I loaded the freezer with Carne Asada that the Market already seasoned. You can fry or grill in minutes and it tastes great. I imagine many ethnic markets are a source for cheaper protein.
