Slice zucchini length-wise into 4-6 strips about 1/4 inch in width. Add to a ziptop bag with the baby bell peppers.
In a small bowl, whisk together olive oil, balsamic vinegar, dried oregano, dried basil, garlic cloves, red pepper flakes, and a pinch each of salt and pepper. Pour into the bag with the vegetables and toss to thoroughly combine. Marinate at room temperature for 10-15 minutes or up to 6 hours in the fridge.
When ready, preheat grill or grill pan to medium-high. Remove vegetables from the bag and, leaving space on the grates between veggies, grill vegetables for 4-5 minutes per side until charred and tender. Set aside on a plate. You may need to do multiple batches depending on the size of your grill/grill pan.
In a bowl, toss cherry tomatoes with olive oil, balsamic, garlic, fresh basil, fresh mint, fresh rosemary, and a pinch of salt and pepper.
Combine goat cheese, lemon juice, garlic, Greek yogurt, and a pinch of salt in a food processor. Whip until creamy. Pour into a small serving bowl.
Set tomatoes and goat cheese on a serving board or platter. Arrange grilled vegetables around the bowls. Fill in the gaps with sliced prosciutto, smoked salmon, or cold cuts otherwise. I also opted to wrap a few peach slices with some prosciutto for J to nibble on. Finish with various summer fruits such as peaches, plums, cherries, grapes, or apricots.
