Avocado-and-Pea Salmon Tartines

Place avocados and peas in a bowl. Using a fork, thoroughly mash. Add lemon juice, chopped mint, salt, and pepper; stir well. Spread 1/4 cup avocado mixture on one side of each bread slice; top each with 1 smoked salmon slice. Arrange radish slices evenly over salmon slices; drizzle with olive oil. Garnish with fresh mint leaves.
