You can use grilled steak, skirt steak, chicken, smoked brisket....I can't think of any grilled or smoked meat that wouldn't taste delicious with this. It's a fabulous way to use up leftover grilled or smoked meat.
ROASTED TOMATOES: Pan roast or grill tomato slices. I place a little olive oil in a non stick skillet, place tomato slices in pan, cook on each side over med high heat for about 5 min per side.
GRILLING: Drizzle olive oil over tomatoes and place on med heat grill. Cook about 3-5 min per side, depending on how hot grill is.
Place tortilla chips on baking sheet sprayed with non stick oil or lined with parchment paper or foil. Sprinkle on cheese, add roasted tomatoes, diced onion and a little more cheese, and steak. Pop under low broiler just long enough to melt cheese. Remove and drizzle with Thai chile paste and cilantro.
