Instructions

Make the potatoes:

Make the dressing:

  1. While the potatoes are cooking make the dressing. Whisk together the mayo, sour cream and milk until smooth. Add the spices and whisk until combined. Add the lemon and whisk again.

Cook the shrimp:

  1. Add a cup of water to the Instant Pot and heat the water on the saute setting. Once it’s boiling add in the shrimp and cook until barely pink. Drain off the water. 
  2. Add 2 Tbsp of butter into the pot and let it melt. Toss in the bell pepper and saute for 2-3 minutes. Add in a pinch of kosher salt. 
  3. Turn off the Instant Pot. 

Assemble:

  1. On each plate add a scoop of potatoes. Drizzle with 1-2 Tbsp of the dressing. Top with a scoop of the shrimp and peppers. Finally sprinkle with a bit of cheddar cheese.
