### 👩‍🍳 How to Make It (Step-by-Step | ~16 min)

| Time | Action |
|------|--------|
| **0–2 min** | Peel and thinly slice the leek into rings. Tear the stale bread into small chunks or pulse in a knife-handful to make coarse breadcrumbs. |
| **2–6 min** | Heat 2 tbsp butter in a large nonstick or cast-iron skillet over medium. Add the leek. Cook, stirring occasionally, until soft and lightly golden (~4 min). Season with a pinch of salt/pepper. |
| **6–10 min** | Push the leek to one side (or wipe the pan briefly). Add the bread chunks/crumbs to the same pan (or use the same pan if there's room) and fry in the leek-butter butter, stirring, until golden and crispy (3–4 min). Transfer to a plate. |
| **10–14 min** | Reduce heat to medium-low. Crack the 4 eggs into the pan around the leek (or scramble them in if you prefer). Cover the pan with a lid or foil. Cook 3–4 min until egg whites are set but yolks are still runny (longer if you like them firm). |
| **14–16 min** | Sprinkle the parmesan over the eggs, cover for 1 min to melt. |
| **Serve** | Slide eggs on top of the leek, spoon the crispy breadcrumbs over and around, grate a little extra parm on top, grind fresh black pepper, and serve immediately. |

### 💡 Why It Works
- **Eggs + leek** cook fast and taste rich/savory.
- **Stale bread + butter + parm** becomes a craveable savory topping (like a mini breadcrumb crumble usually found on pasta or casseroles, but all stovetop).
- **No oven** needed—everything happens in one skillet.
- **Serves 2** comfortably; the leek spreads out, and 2 eggs each is a solid dinner portion.
- **Vegetarian** ✅ (eggs + dairy are fine).

### 🔁 Quick Variations (if you have extras)
- Add a splash of hot sauce or soy sauce to the leek.
- If you have a handful of spinach or wilted greens, toss in with the leek.
- Swap parmesan for pecorino or any hard cheese you have.
- Serve with a simple green salad or leftover roasted veggies if you have them.
