Yam-Burgers

I went googling this idea, and came up with a hamburger place in San Juan, Puerto Rico.   I didn't find any recipes for combined ground beef and sweet potato patties, which is what I had in mind.  There are plenty of vegetarian and vegan yam burgers online.  I could have made this into a casserole with noodles and called it "yamburger helper".  Changed plans - and made things much easier on myself - by turning this into a burger on sweet potato toasts.

1 lb 80/20 ground beef
*1/4 C minced red onion
*1 clove garlic, minced
salt and white pepper
1/4 tsp paprika
1 fat sweet potato, about 3/4 lb
olive oil
serving garnishes like lettuce, cilantro, avocado, Greek yogurt...

1.  In a bowl, knead together ground beef, minced onion, and garlic.  Sprinkle in a bit of salt, white pepper, and the paprika.  Refrigerate while you prepare the sweet potato.

2.  Line a baking sheet with parchment or a silicon mat and start preheating the oven to 400º.  Slice the potato into 1/4" thick slabs big enough to rest a small burger on.  I did it on an angle to increase surface area.  Brush both sides with oil and bake for 10 minutes.  Flip and cook other side another 10 minutes.

3.  You can either wait until the toasts are done and use the broiler, or just make 4 burger patties (on foil for easy clean-up) and put them on the top rack of the oven for 10-15 minutes.  Flip halfway through.

4.  Build burgers with desired garnishes, but be aware you're probably going to want to use utensils for this one.  The toasts can't support a whole quarter-pound burger.  Serve warm.
