Yukon Gold Frites: Thinly slice potatoes lengthwise to form a traditional thin chip. Toss into a hot pot of good frying oil (canola or peanut). Fry until partially cooked. Remove from oil and let drain on a paper-towel covered plate. Sprinkle with a homemade Texas-style dry rub spice (sea salt, white pepper, celery salt, ground cumin, paprika, black pepper, garlic powder, chili powder, lemon zest, cayenne pepper and dry mustard). Toss chips on a hot grill and cook through until brown, crispy, with nice grill marks. Serve with chipotle aioli to dip.
Whisk all ingredients together.
Grilled Chayote: Slice 1 to 2 chayote lengthwise like the potatoes. Brush each side with melted butter and season with salt and pepper. Cook on a medium-high grill turning frequently to make crisscross marks on both sides. When fork-tender, remove from grill and season again.
Grilled Roma Tomatoes: Slice 2 Roma tomatoes in half; core the center to remove seeds and to make a pocket. Sprinkle with salt and pepper. Brush with olive oil. Fill pockets with pesto, about 2 tablespoons each, and sprinkle on some grated Parmesan. Grill tomatoes until tender but not falling apart, about 5 minutes if grill is very hot. Sprinkle with a bit more grated Parmesan, and serve.
