Preheat oven to 350. Season steak with Red Boat Salt or kosher salt and let stand at room temperature until ready to grill.
Make roasted tomatoes: Place cherry tomatoes on a baking sheet, drizzle with olive oil and sprinkle with kosher salt and cracked pepper, turning to coat. Roast tomatoes 30 minutes, shaking pan halfway through, until tomatoes are semi wrinkled and some of them have split open. Set aside.
Make Jammy Eggs while the tomatoes roast: Bring several inches of water to a boil in a sauce pan fitted with a steamer basket. Once it boils place eggs in the steamer basket and close the lid. After 8 minutes move eggs from pan into a bowl of ice water and let cool 15 minutes before peeling.
Make dressing of your choice (ingredients for both options are in notes): Whisk all ingredients except for oil in a bowl. Gradually whisk in oil until emulsified. Adjust seasoning to taste.
Cook the steak either on the grill or stove-top in a heavy pan (cast iron works great). If cooking in a pan, coat your pan with 1 Tablespoon of oil. You'll cook at a fairly high heat, only turning once, for 3-5 minutes per side depending on the desired final temp. Let the steak rest for 5 minutes before slicing across the grain at a slight angle. *See notes for steak temps*
Build your salads: While the steak rests divide salad greens between 4 plates. Drizzle each serving with a tiny bit of olive oil (about 1/2 tsp) and season lightly with salt (preferable flaky salt) and cracked pepper. Divide cucumbers, roasted tomatoes and goat cheese over the center. Arrange 1/2 of an avocado and 2 egg halves off to the side of each salad. Divide steak slices between salads, fanning over the top. Drizzle lightly with dressing and pass the rest at the table.
*You can make the eggs, roasted tomatoes and salad dressing up to a week ahead for an even faster meal
