Sriracha burgers with guacamole & caramelized onions

On Tuesday we had Sriracha burgers with caramelized onions. I used ground turkey instead of ground beef. Also, it was raining out so we pan fried the burgers instead of grilling. It truly tasted much better than it looked. Maybe next time, we'll get a good shot. :)
Below is how we did this, but here is the original link from BrokeAssGourmet.

Sriracha burgers with guacamole & caramelized onions

2 tbsp butter
1 medium onion, half sliced thinly, half diced finely
1 lb ground turkey ( or ground beef )
2 tbsp Sriracha (or more if you it extra-spicy)
2 tbsp coconut aminos
1 handful fresh cilantro leaves,
3 cloves garlic, minced
1 tsp freshly-ground black pepper
your favorite guacamole

Preheat a grill, grill pan or cast iron frying pan over medium-high heat.

Melt butter in a medium frying pan over medium-low. Add the sliced onions and cook for 18-20 minutes, until caramelized.

While onions cook, combine the chopped onions, beef, sriracha, soy sauce coconut aminos, cilantro and garlic. Use your hands to mix well and form into 4 equal-sized patties.

Cook the burgers to desired doneness and serve over mixed greens or alone, topped with a generous dollop of guacamole and a few caramelized onions.

Serves 4.
