If using wooden skewers, soak in water for 10–15 minutes to prevent scorching. Metal skewers? You're already winning.
Cut hot dogs into 1-inch bites. Chunk the cucumber into sturdy pieces; leave cherry tomatoes whole for juiciness.
Toss cucumbers and tomatoes with a little olive oil, plus salt, pepper, and optional spices. Keep it light—these veggies don't need a lot to shine.
Alternate cucumber, hot dog, tomato, repeat. Leave a little space between pieces so they sear, not steam.
Cook your way:
Sprinkle herbs after cooking for freshness. Add a crack of pepper and a pinch of flaky salt if you're feeling fancy.
Mustard is classic, but yogurt-based dips make it feel gourmet without the guilt, IMO.
