heat your grill or big green egg to medium-high heat (350-400F). If you don't have access to a grill, place the meat in a cast iron skillet under the broiler as a decent substitute
Grill over direct heat, turning occasionally until meat reaches internal temp of 125 F for medium rare (is there any other way?). Allow to rest for 5-10 minutes before slicing against the grain.

Sauté tomatoes, garlic and almonds in cast iron skillet with a tbsp of olive oil until tomatoes start to shrivel and break apart slightly.
combine the roasted red pepper, garlic, tomatoes, almonds along with the quarter cup olive oil, vinegar, and pepper flakes in a food processor and buzz until smooth. Add salt to taste.
