Yes — that’s basically a skillet frittata and some fancy toast. Twenty minutes, one pan, zero oven.

**One-Pan Leek & Parmesan Frittata with Crispy Buttered Toast**

**The 20-minute plan**

1. **Prep (3 min)**  
   - Halve the leek lengthwise, rinse thoroughly between the layers (they hide grit), then slice into half-moons.  
   - Beat the 4 eggs with a big pinch of salt, pepper, and about half the parmesan.  
   - Slice the stale bread thick (1-inch is perfect).

2. **Toast the bread (4 min)**  
   - Butter both sides of the bread.  
   - Heat a large nonstick skillet over medium, toast the bread until golden and crisp on both sides.  
   - Set aside on a plate (you’ll warm it later or serve room-temp; it’ll still be great).

3. **Soften the leeks (5 min)**  
   - Melt a tablespoon of butter in the same skillet.  
   - Add the leeks with a pinch of salt. Cook over medium, stirring occasionally, until soft and sweet, about 4–5 minutes.

4. **Set the eggs (6 min)**  
   - Reduce heat to low. Spread the leeks out evenly.  
   - Pour the eggs over them and sprinkle the rest of the parmesan on top.  
   - **Cover tightly** (lid or foil) and cook 5–7 minutes until the center is just set — no oven needed, the steam does the work. If the top is still a little wet, give it another minute or two off the heat.

5. **Serve**  
   - Slide the frittata onto a board or cut wedges right in the pan. Serve with the hot/crispy toast.

**Quick tips**

- **Stale bread is a feature, not a bug** — it toasts crisp and buttery instead of getting soggy.
- **Covering is the whole trick** for no-oven frittata. Don’t skip it.
- **Parmesan check:** If your girlfriend is vegetarian in the strict sense (no animal rennet), just confirm the parmesan is vegetarian-friendly. Most supermarket parmesans are, but some traditional ones aren’t.

Dinner’s done. White wine optional, strongly recommended.
