Grate the cucumber on a box grater or with your food processor. Squeeze handfuls of the grated cucumber to get the extra water out.
Mix all the ingredients into the yogurt and give everything a gentle stir. Set aside in the refrigerator until you serve the meal.
Start by cooking the pasta per the package directions in salted water, drain and toss with a drizzle of olive oil so the grains don’t stick. While the pasta is still hot add the thinly sliced shallots (slicing the shallots is the perfect job for your mandolin) and stir, lightly cooking the shallot with the pasta’s residual heat. Let the pasta cool a little while you make the dressing.
Stir all the dressing ingredients together and then pour the over the pasta. Add the mint and the rest of the veggies to the pasta and toss gently. Taste the salad and adjust the flavors to your preference. You can make the salad right before you grill the shrimp or whenever you have time and let it rest in the refrigerator. It will taste just as good warm or cold.
Grilling the Shrimp
When you are at the fish market take a look at the different offerings, don’t overpay for pre cleaned and deveined shrimp. It’s really not that time consuming to clean the shrimp yourself. Just be sure to remove the entire vein from the back of the shrimp and give them a rinse before you cook them so they are nice and clean.
In a non-reactive container mix the ingredients for the marinade together. Then add the shrimp. The shrimp will only need to marinate for about 10 minutes, if you let them sit in the marinade too long the acid in the marinade will start to cook the shrimp and you will end up with ceviche.
Place the shrimp on a very hot grill. The shrimp will only take about 3 minutes total to cook, so your grill master needs to have some quick moves. When the shrimp come off the grill squeeze some lemon over them and sprinkle with a little salt.
I serve the shrimp over a bed of the orzo pasta with a dollop of the tzatziki and a wedge of lemon. As I have mentioned I have served this meal cold, warm or hot depending on my schedule for that day, so don’t forget this recipe if you need an elegant lunch.
