To make the dressing, combine all ingredients in a small glass or pourer to whisk until smooth. Season with salt and black pepper to taste.
To make the steak, pat all sides dry with a paper towel. Season both sides generously with salt and black pepper.
Heat up a cast iron or stainless steel skillet over medium high heat until very hot, about 2 to 3 minutes. Add the olive oil then lay down the steak away from you to prevent any splattering.
Let sear untouched for 3 to 4 minutes, then flip to cook an additional 3 to 4 minutes. In the last minute of cooking, add the butter and garlic to baste. Remove from the heat to rest at least 5 minutes before slicing into strips then into bite-sized squares.
In a large bowl, combine the chopped steak, romaine, radicchio, corn kernels, chopped avocado, halved cherry tomatoes, finely chopped red onion and crumbled feta. Drizzle with the dressing then toss until well combined.
