Although my grill times were longer than what the book suggested, the technique worked well for some vegetables: namely, Portobello mushroom slices, zucchini (aka courgette) slices, and thick asparagus shoots. (Beware of slices that are too thin, which will fall apart, and too thick, which will not cook through.)
The grilled vegetables thus prepared can be eaten as they are, preserved for a week or two in a jar topped off by olive oil, or turned into a salad. The latter can benefit from the addition of fresh vegetables, such as tomatoes and basil, feta cheese, olives, and a dressing consisting of olive oil, lemon juice, and chili paste.
Salad:
- grilled veggies (zucchini, mushrooms, ...)
- tomatoes, diced
- basil, shredded
- green & black olives
- feta cheese, crumbled
- 6 Tbsp olive oil
- 2 Tbsp lemon juice
- 1/2 tsp chili paste
