01 - Bring the vegetable broth to a gentle boil in a medium saucepan. Stir in the rolled oats, reduce heat to low, and simmer uncovered for 7-8 minutes, stirring occasionally, until creamy and tender.
02 - Heat olive oil in a large skillet over medium heat. Add the finely diced yellow onion and sauté for 2-3 minutes until softened and translucent.
03 - Add the sliced cremini mushrooms to the skillet. Cook for 4-5 minutes, stirring occasionally, until they release their moisture and develop a golden-brown color.
04 - Stir in the minced garlic and cook for 30 seconds until fragrant. Add the smoked paprika and red pepper flakes if using, tossing to combine.
05 - Add the fresh baby spinach to the skillet and cook for 1-2 minutes, stirring constantly, until just wilted but still vibrant. Season with sea salt and freshly ground black pepper to taste.
06 - Divide the creamy cooked oats evenly between two bowls. Top each portion generously with the sautéed spinach and mushroom mixture.
07 - If desired, crown each bowl with a freshly fried or poached egg, a sprinkle of grated Parmesan cheese, and a garnish of chopped fresh chives or parsley. Serve immediately while hot.
