Veggie-Loaded Egg White Breakfast Skillet (American Diner Style)

A classic American breakfast skillet made lighter with fluffy egg whites and a rainbow of veggies—high-protein, high-fiber, and satisfying without feeling heavy.

Ingredients

• 2 tsp olive oil (or other neutral oil)
• 1 small onion, diced
• 1 bell pepper, diced
• 1 medium zucchini, diced
• 2 cups baby spinach (packed)
• 1 cup cherry tomatoes, halved
• 1 tsp garlic powder (or 2 garlic cloves, minced)
• 1/2 tsp smoked paprika
• 1/2 tsp dried oregano
• 8 large egg whites (about 1 cup)
• 1/2 tsp kosher salt, plus more to taste
• 1/4 tsp black pepper
• 1/2 avocado, sliced (for serving)
• 2 slices whole grain toast (for serving)

Method

• 1

  Step 1: Sauté the base

  Heat oil in a large nonstick skillet over medium-high heat. Add onion and bell pepper with a pinch of salt. Cook, stirring, until the onion turns translucent and the peppers soften, about 4 minutes.

  Step 2: Build the veggie skillet

  Add zucchini, garlic powder, smoked paprika, and oregano. Cook until the zucchini is crisp-tender and you see golden edges, about 3 minutes. Add cherry tomatoes and cook 1 minute just to soften (you want them juicy, not collapsed).

  Step 3: Wilt the spinach

  Add spinach in handfuls, tossing until just wilted, about 1 minute. Spread everything into an even layer so the eggs cook evenly.

  Step 4: Add egg whites (don’t overcook!)

  Reduce heat to medium. Pour in egg whites, season with salt and pepper, and let sit 20–30 seconds until you see the edges start to set. Then gently push and fold with a spatula, making soft curds. Cook until just set but still glossy, 2–3 minutes (they’ll keep cooking from residual heat).

  Step 5: Serve

  Divide between plates. Top with sliced avocado and serve with whole grain toast.

Tips

• **Keep egg whites tender:** Pull them when they’re *just* set and slightly shiny—dry egg whites happen fast.
• **Make it meal-prep friendly:** Cook the veggie base ahead (up to 4 days refrigerated). Reheat, then add egg whites fresh in the morning.
• **What to serve with it:** Fresh fruit on the side or plain Greek yogurt (if you have it) makes this a complete, protein-forward breakfast.
