For queso: Heat butter and olive oil, over medium heat, in medium saucepan. Add chopped poblano peppers and saute 3-5 minutes, stirring occasionally. Reduce heat if browning or cooking too fast.
Reduce heat to medium low, add Velveeta, cream cheese, half-and-half, or milk and chopped jalapeno. Stir occasionally, until cheeses are melted and mixture is smooth and combined. Add green chilies, chopped tomato and black pepper, to taste. Stir to combine.
Remove from heat, if making ahead, or reduce heat to lowest setting while putting together nachos.
For nachos: preheat oven to 350F. Spread tortilla chips, in a generous single layer on large, rimmed, baking sheet. Top with pinto beans and chorizo sausage chunks, or your choice of toppings. Bake for 8-10 minutes until everything is heated through. Remove from oven, and spoon warm P-P-P-Peppered Queso, on top. Garnish with sliced green onions and thin jalapeno slices, or whatever tickles your fancy. Scoop onto serving plates with pancake spatula and indulge. Muchas gracias!
