Homemade is better than any of that fast food. Jazz up that burger. Just for adults! I got this from Pioneerwoman and we just love it. The various flavors just somehow work perfectly. If you like this recipe see others of mine at mybestcookbook.wordpress.com
Add salt and pepper to the meat and mix gently. Make into three patties. Cook until done in a saute pan or on the grill.
Slice the onion from root to stem, and then lay each half flat and cut from root to stem into slices. Saute in a pan with a bit of butter and olive oil until caramelized. (This can take up to 30 minutes)Don't be afraid to scorch them a bit at the beginning but then turn back and cook gently until soft and sweet. Set aside when finished until ready to assemble.
Crumble the blue cheese and set aside
Mince the jalapeno (with or without the seeds) and mix with the mayonnaise. Set aside.
When nearly ready to eat, butter the rolls, and brown/grill until butter melted and they are lightly toasted.
Place the burger on the bun, add a tablespoon or so of the cheese, cover with a mound of the onions. Slather the top with the mayo, and then sit down and eat.
