Preheat oven to 375F.
Add both cheeses to a 6-inch cast iron skillet and toss together. Place in the oven and bake until melted and bubbly, about 15 minutes. Turn the oven to broil and cook for 3-4 minutes longer or until the top is golden brown.
While the cheese melts, dice the tomatoes into 1/4-inch pieces. Place the diced tomatoes onto a paper towel to soak up any extra liquid.
To serve top the melted cheese with diced tomatoes, green onions and cilantro leaves. Serve immediately with tortilla chips for dipping.
