tri tip tacos

i found out yesterday afternoon that i'd be hosting dinner at my house today for 4 guests.  i decided to make a 3lb tri tip since it'd been staring at me in the fridge for the past few days.  i wasn't going to have time to come home and grill it between work and the arrival of our guests so was stumped on what to make with it.  when one of my roommates had the idea of cooking it in the crock pot.  at first i thought no way i'm not going to waste this gorgeous cut of beef.. i mean who cooks tri tip in a crock pot?  i couldn't pulled out some frozen chicken and done a more hands on type of dinner but i didn't really have the extra time to dedicate.  so i sent up a prayer to cro-po heaven and went with the set it and forget it motto.  i thoroughly trimmed the beef and rubbed it with a mixture of paprika, chili powder and cumin.  then i added a bottle of this marinade i bough awhile ago and had been meaning to try called lawry's tequila lime marinade (also it'd been a while since i purchased this so when i looked it up it shows it's discontinued) and about 1 cup of water.  i cooked it on low for the first 3 hours and on high for the next 3 hours.  when i opened the cro-po the beef was so tender that i only needed 2 forks to shred.. and oh man was it was delicious!!!
