Season Tri-tip cubes and ground beef well with kosher salt and grey in the dutch oven with a little olive oil over medium heat for a minute or two, then drain in a colander. Rinse most of the fat off under the faucet (trust us).
Drain almost all of the fat from the dutch oven, too.
Add the rinsed meat back in the dutch oven, add tomato sauce and beef broth and bring to a low boil for 5 mins, then reduce to a low simmer.
