Take everything but the roast and put it in a blender. Blend until onion is all ground up.

Add some of the sauce to bottom of crock pot. Place roast in crock pot and pour the rest of the sauce over meat.

Slow cook for 8-10 hours on low.

Use fork or tongs to shred the beef once cooked. It will essentially fall apart. Your heart will skip a beat.

A note about the peppers: they are a slow heat that builds on you, so you may not want to use the whole can if you aren’t big on spicy stuff.
