Bring a large saucepan of water to a boil with plenty of salt. Add ⅔ cups farro and cook for 15-20 minutes, until cooked. Drain well and shake to get most of the liquid out.
While that is cooking, prepare the eggs. In a large saucepan or stock pot, add about 1" water and a steamer basket. Cover and bring to a boil. Once boiling heavily, gently lower the eggs into the pot. Cover and cook the eggs for about 8 minutes to get a semi-soft interior texture.
Preheat oven to 450ºF, with a rack in the upper third of the oven. Trim ends from the radishes and cut into ½” wedges. Trim the woody ends from the asparagus. Halve the Fresno chile, discard the stem and seeds and finely chop.
In a small bowl, whisk 2 tbsp oil, 1 tbsp vinegar, a ¼ tsp each sugar, salt and pepper. Stir in the chopped pepper and set aside to marinate.
On a rimmed baking sheet, toss the asparagus and radishes with 1 tbsp oil and season with salt and pepper. Roast on the upper rack until the asparagus is bright green and everything is cooked, about 8-10 minutes.
Trim the scallions and thinly slice. Roughly chop dill fronds and tender stems (or thyme leaves). Crumble the feta into a small bowl and add the ¼ cup sour cream and mash together with a fork. Stir in the scallions, dill/thyme and 2 tbsp water. Season with salt and pepper.
Serve farro, topped with radishes and asparagus, then topped with the feta cream mix, then the eggs (sliced in half). Sprinkle on pepitas and drizzle on the chile and vinaigrette.
