How to Make It
Preheat oven to 425°. Toss together shrimp, black pepper, 1/4 cup oil, 1 tsp. salt, and 1 tsp. lime zest. Spread shrimp in a single layer on a parchment paper-lined baking sheet; bake 5 minutes or until shrimp are pink and done.
Meanwhile, process mint, next 3 ingredients, 1 (5-oz.) package spinach, and remaining 1 1/4 tsp. salt and 1 tsp. lime zest in a food processor until finely chopped. With processor running, pour remaining 1/4 cup oil through chute in a slow, steady stream, processing until combined.
Toss remaining 1 (5-oz.) package spinach with warm rice. (Spinach will wilt slightly.) Stir pesto into rice mixture; sprinkle with almonds. Top with shrimp.
