Ingredients You’ll Need
- 2 slices good bread (ciabatta, sourdough, or whatever you love)
- 1 ripe tomato, sliced (heirloom or beefsteak if you’re feeling bougie)
- ½ English cucumber or 1 small regular cucumber, thinly sliced
- 3–4 tbsp crumbled feta cheese
- A few fresh basil leaves, torn
- Thin slice of red onion (optional, but recommended)
- 1 tbsp extra-virgin olive oil
- 1 tsp lemon juice or red wine vinegar
- Salt and black pepper to taste
- Optional: a smear of hummus or mayo, or a sprinkle of za’atar
Step-by-Step Instructions
- Prep your veggies first. Wash and slice the tomato and cucumber thinly so they layer nicely and don’t bulge the sandwich like awkward furniture in a tiny apartment.
- Make a quick dressing: whisk together olive oil, lemon juice (or vinegar), a pinch of salt, and pepper. Don’t overdress—you want flavor, not soggy bread.
- Give the bread a little love. Toast it lightly if you want crunch or char it on a hot pan for that smoky flair. Toasting helps prevent sogginess, especially if your tomatoes are juicy.
- Optional: spread a thin layer of hummus, mayo, or softened butter on one or both slices. This adds creaminess and acts like a flavor buffer so the feta doesn’t overwhelm everything.
- Layer the tomato slices first so the cucumber doesn’t slide around. Drizzle a bit of the dressing over the tomatoes to coax out the flavor.
- Add the cucumber slices, then scatter the red onion and torn basil leaves. The basil is key—don’t skip it unless you hate joy.
- Sprinkle the crumbled feta evenly. Use good feta; it’s the salty backbone of the sandwich. If your feta is very dry, crumble it a bit with your fingers for better distribution.
- Top with a pinch of salt and a few cracks of black pepper. Taste one edge—adjust if it needs more acid or salt. If it feels flat, add a tiny splash more lemon or vinegar.
- Close the sandwich, press gently, and cut diagonally because triangles just taste better. Serve immediately so the bread retains its texture.
Common Mistakes to Avoid
- Using watery tomatoes straight from the fridge—let them come to room temperature for better flavor and less sogginess.
- Overdressing the vegetables—too much oil or vinegar will make your sandwich a mess. Light is right.
- Skipping toast—cold, soft bread plus juicy tomatoes = structural sadness. Toast or grill for durability.
- Adding too much salt after feta—taste first. Feta can be pretty salty on its own.
Alternatives & Substitutions
If you want to switch things up, go for it. Try vegan feta or mashed avocado to make it dairy-free. Swap basil for mint or arugula if you like peppery greens. Prefer warmth? Grill a slice of halloumi and use it instead of feta for a melty, salty twist. No good bread? Pita or a wrap works fine—just expect a slightly different vibe.
Love heat? Add chili flakes or harissa. Want Mediterranean territory? Toss in olives or a smear of tapenade. Experimentation encouraged.

FAQ – Frequently Asked Questions
-
Can I make this sandwich ahead of time?
Short answer: yes, but don’t build it too early. Assemble up to 30 minutes ahead and keep it wrapped. Pro tip: stash the cucumber and tomato separately if you plan more than an hour—no one likes soggy bread.
-
What bread should I use—fancy or basic?
Both work. Rustic sourdough adds crunch; a soft ciabatta soaks up flavors. IMO, go with what makes you smile. FYI: toast lightly for extra structure.
-
Can I swap feta for something else?
Totally. Goat cheese or ricotta are lovely if you want creaminess. If you need vegan, try a salty almond-based feta or a firm tofu marinated in lemon and salt.
-
How do I keep the cucumber from making everything soggy?
Pat the slices dry with a paper towel and slice thin. Less moisture = happier sandwich. Also: a light smear of butter or mayo creates a moisture barrier—simple science.
-
Want a flavor boost—add herbs or skip them?
Herbs are friends. Basil or dill lifts the whole thing. If you’re feeling bold, a sprinkle of crushed red pepper adds a cheeky kick. But no pressure—it’s delicious either way.
-
Is this lunch-worthy for packing?
Yes, if assembled smartly. Pack components separately and build at lunchtime. Otherwise, toast the sandwich and eat it warm within a couple hours for best results.
