Instructions
Marinate the Steak
Add the salt and pepper to a gallon zip-top bag, then add the olive oil, balsamic vinegar, Worcestershire sauce, and minced garlic. Roll the top of the bag back so it stands upright while you pour.
Gently shake the bag to combine the marinade.
Add the flank steak halves, press out most of the air, seal the bag, and move the steak around so the marinade coats it all over.
Refrigerate 30 minutes to 4 hours. Two hours is ideal.
Make the Chimichurri
Pull the leaves from the parsley stems, gather them into a bundle, and give them a rough chop until you have about 1/2 cup.
Strip the oregano leaves by pinching the stem and sliding backward, then chop until you have about 2 tablespoons.
In a bowl, combine the chopped parsley, chopped oregano, crushed red pepper, red wine vinegar, minced garlic, and olive oil. Season with salt and pepper to taste and stir well.
Set aside at room temperature while you cook so the flavors have time to meld.
Prep and Cook
Heat a cast iron skillet over medium to medium-high heat and add 2 tablespoons of olive oil.
Thinly slice the red onion, slice the green onions all the way into the white parts, and reserve a small amount of green onion for garnish.
Snap the woody ends off the asparagus by bending each spear until it breaks naturally.
Place the marinated steak directly into the hot skillet and cook 4 minutes per side for medium rare. Add 1 to 2 extra minutes per side for more doneness.
While the steak cooks, slice the tomatoes in half lengthwise.
Remove the steak from the skillet and let it rest for 10 minutes.
Add the remaining 1 tablespoon of olive oil to the skillet, then the red onion and green onion. Cook 3 to 4 minutes until softened.
Add the asparagus and cook about 5 minutes until tender.
Add the tomatoes for the final 40 seconds, just until they begin to burst.
Bring It Together
Turn off the heat. Return the rested steak to the skillet on top of the vegetables and pour in any collected juices.
Drizzle about half the chimichurri over the steak and vegetables, reserving the rest to serve at the table.
Let the skillet sit off the heat a couple of minutes, then plate and sprinkle with the reserved green onions.

Notes
Flank steak takes a marinade beautifully, but sirloin, flat iron, or skirt steak all work well here.
Don't marinate longer than 4 hours — the acid in the vinegar will start to change the texture of the meat.
For temperature accuracy, pull the steak at 130°F for medium rare or 140°F for medium.
The chimichurri can be made up to a day ahead. Keep it covered in the refrigerator and bring it to room temperature before serving.
To double this for four, use a whole flank steak and sear it in two batches so the pan doesn't get crowded.
The crushed red pepper gives warmth rather than heat. Cut it to 1/2 teaspoon or leave it out if you're sensitive to spice.
