Why You'll Love this Breakfast Vegetable Stack:
Fresh and savory: A vegetable-forward breakfast that feels satisfying without being heavy.
Simple preparation: Roasting and sautéing keep the steps straightforward and approachable.
Balanced flavors: Creamy dill mayo and tangy feta complement the roasted vegetables.
Great for brunch: An easy option that looks impressive but doesn't require much effort.
Naturally gluten-free: Made without bread or grains, making it suitable for gluten-free diets.
Key Ingredients:
- portobello mushrooms. These provide a hearty, meaty base with a rich umami flavor that stands out in the stack. Large cremini mushrooms offer a slightly milder taste if you prefer a gentler flavor profile.
- zucchini. Thinly sliced zucchini adds a tender, fresh layer that complements the mushroom base. Other summer squashes like yellow squash can work similarly.
- baby spinach. Crisp and tender baby spinach adds a fresh, vibrant touch to the stack, bringing a burst of green that lightens the rich flavors of the other vegetables.
- mayonnaise. Enhance your dish by using our homemade mayonnaise recipe, which delivers a creamy, personalized touch that perfectly ties all the flavors together.

Easy Substitutions & Variations:
- Swap the cheese: Use goat cheese or shaved Parmesan in place of feta for a different tang and texture.
- Change the greens: Baby arugula or kale can replace spinach for a slightly peppery or heartier bite.
- Make it dairy-free: Use a dairy-free mayo and skip the feta, or replace it with a plant-based feta alternative.
- Add protein: Top the stack with a soft-poached or fried egg for a more filling breakfast.
- Change the herbs: Swap dried dill for fresh dill, chives, or parsley to adjust the flavor profile.

How to Make Breakfast Vegetable Stack:
- Preheat your oven to 400°F. Clean the portobello mushrooms by gently wiping them with a damp cloth. Remove the stems and, if desired, scrape out some of the gills for a cleaner presentation. Lightly season both sides with salt and pepper.
- Place the mushrooms on a baking sheet and roast for about 10 minutes, until they begin to soften.
- While the mushrooms roast, lightly sauté the zucchini slices and red bell pepper in a non-stick skillet over medium heat for 3-4 minutes until just tender. Add the baby spinach during the last minute of cooking until it wilts slightly. Season lightly with salt and pepper.
- In a small bowl, mix the mayonnaise with dried dill. Adjust salt and pepper to taste.
- On each roasted mushroom cap, layer the sautéed zucchini, red bell pepper, and spinach. Drizzle or spread the dill mayonnaise over the vegetables, then sprinkle the crumbed feta cheese and microgreens on top.
Recipe Notes & Tips:
- Prep the mushrooms gently: Wipe portobello mushrooms clean with a damp cloth instead of rinsing to prevent them from absorbing excess moisture.
- Don't overcook the vegetables: Sauté just until tender so the zucchini and peppers keep some texture and color.Season lightly: Feta and mayonnaise add saltiness, so taste before adding extra salt.
- Assemble just before serving: Stacking right before serving keeps the vegetables vibrant and prevents sogginess.
- Serving Suggestions: Serve this breakfast vegetable stack alongside our Greek Yogurt Bagels or Iced Matcha Latte for a more complete brunch-style meal.

How to Store:
- Refrigeration: Allow any leftover stacks to cool completely, then store in an airtight container in the refrigerator for up to 1-2 days.
- Freezing: Not recommended, as freezing can negatively affect the texture and moisture of the vegetables and mushrooms, leading to a less appealing dish when thawed.
- Reheating: To preserve the texture and flavor of the vegetable stack, reheat it in a preheated oven at 300°F for 10-15 minutes until warmed through, rather than using a microwave which can make the vegetables soggy.
