Using a mason jar or small bowl, whisk together the vinegar, while slowly pouring in the olive oil and continue to whisk together. Season with the salt and pepper and whisk again. Set aside.

Preheat your oven to 425 degrees. Line a baking sheet with foil or parchment paper. Pat the salmon dry with a paper towel and place on the prepared baking sheet. Drizzle some olive oil over the top of the salmon; just enough to coat the salmon, don't over do it. Feel free to rub the olive oil over the salmon with your fingers or a pastry brush. Season with salt and pepper.

Roast for about 4 to 6 minutes per half-inch thickness of salmon. If you see white stuff around the edges of your salmon, you've cooked it for too long. Allow to cool for a minute or two and break into chunks for the salad.

To plate: arrange the cooked salmon chunks and roasted red potatoes on top of a full bed of fresh greens. Add on the hard boiled eggs and tomatoes. Garnish with the microgreens, drizzle on some dressing and enjoy!
