2 Mix together the tomato paste, dried basil or pesto, water, marjoram, salt and pepper. Spread this paste evenly over the surface of the smaller square, trying to keep the edge clean. Cut each of the tomatoes and the onion into 6-8 small wedges, and slice the capsicum into strips about 1cm wide. Halve the zucchini lengthwise and cut into thin (5mm) ribbons.
3 Combine the vegetables, garlic (if using) and basil leaves in a plastic bag or bowl. Add the olive oil, and stir gently until the vegetables are well mixed and evenly coated with oil.
4 Arrange the prepared vegetables over the paste-covered base, then sprinkle the tart evenly with crumbled feta. Season with salt and pepper to taste, then bake at 200C for 20-25 minutes, or until the crust is golden brown.
Serve hot, warm or cold with a green salad or as part of a picnic buffet.
