Its soo easy
Any kind of beef roast any size
one packet of lipton onion dry soup mix
one coup water
carrots and potatos if you wish
what I usly do is put the roast in frozen the night before and cook it all night and next day (really falls apart then) on low I add carrots and potatos next day.
but you can unthaw and put it in and cook it on low for 8 to 10 hours depending on the size of the roast
