I first found this recipe on the Crockpot Lady’s blog earlier in the year when I first started menu planning. It’s quickly become a family favorite! Do NOT forget the limes. I made that mistake the first time I made it. You really need a little citrus to cut the creamy peanut butter sauce. Leftovers are great, too!

1.5-2lbs pork tenderloin
1 onion, sliced in rings
1/4 cup soy sauce
1/4 cup brown sugar
3 tablespoons white wine vinegar (I have used apple cider vinegar in a pinch with no issues)
3 tablespoons water
2 garlic cloves, chopped
1/2 cup creamy natural peanut butter
2 tablespoons chopped peanuts (garnish; optional)
1 lime, cut in wedges (garnish; optional)

Use a 4-6 quart crockpot. Put onion slices into the bottom of your crockpot. Put the pork on top. Add brown sugar, soy sauce, vinegar, water, garlic, and peanut butter. No need to stir–the peanut butter needs to melt before you can do so. Cover and cook on low for 8 hours, or on high for 4-6. The pork will be more tender the longer you cook it. 1 hour before serving, flip the meat over in the crockpot to allow the other side to soak up the peanutbuttery goodness. Garnish with chopped peanuts, and serve with lime wedges. The lime juice mixed with the peanut butter is delicious.
