I didn't think the meat mixture was too spicy at all - must be a subjective taste I guess.. Anyhow - I loved these nachos! I much prefer the cheese sauce over melted cheese, which hardens quickly and leaves you with one big welded nacho.. Velveeta is the best! I also used my own fresh-fried corn chips, which I suggest people do to get the most wonderful nacho ever. (Just slice up some fresh corn tortillas and deep-fry till crisp).. My toppings were diced tomato, green onion, sliced black olives and pickled jalapeno slices.. guac and sour cream. Delicious.
I think the amount of cayenne pepper and red pepper flakes is way too much. Be very careful to reduce these tremendously!
