Slow Cooker Baked Ziti

Another recipe I'm trying out this week:

1 bag/box penne pasta

1 jar marinara sauce

1 med onion

1 bell pepper

1lb ground beef, cooked & drained

1 bag shredded cheese

Mix cooked beef, veggies and sauce together.  Spray crock pot with cooking spray (or use a liner).  Rinse uncooked pasta in a colander.  Layer crock with pasta, meat/sauce mixture and cheese.  Repeat.  Make sure all noodles are fully covered with sauce.  Cover and cook on low 4-5 hours.  

*****UPDATE*****
This one didn't turn out so well.  You definitely need to add about 1/2 c of water to this one.
