Heat oven to 425 degrees and line a large, rimmed baking sheet with silicone or parchment.
Add the diced vegetables, garlic, and walnuts (if using) to a large bowl and toss with oil, honey, salt, pepper and spices until even coated. Spread out in a single layer on prepared baking sheet.
Cook vegetables for 20-25 minutes, stirring once halfway through, until tender and browned.
Meanwhile, cook the bacon in a skillet until crisp. Remove to a towel-lined plate and crumble when cool enough to handle. Set aside.
Drain all but 1 tablespoon of bacon fat from the skillet and in the last few minutes of the vegetables roasting, fry the eggs until cooked to your liking.**
Top the roasted vegetables with the fried eggs and sprinkle the crumbled bacon and feta over all.
Serve with biscuits or rolls drizzled with more honey.
Notes
*Or any combination of your favorite root vegetables that equal about 6 cups cut.**Alternate method for cooking eggs: To cook with along the vegetables in the oven, lower heat to 400 degrees after the vegetables are tender, remove the pan from the oven and make 4 small nests (or how many you need) in the vegetables. Crack an egg in each hole, and put the pan back in the oven. Cook for additional 10 minutes until the eggs have cooked through to your desired doneness.
