Make the Neptune Filling: Add the chive onion cream cheese, chopped surimi, chopped cooked shrimp, sliced green onions, and soy sauce to a food processor. Pulse until the mixture is combined but still slightly chunky.
Fill the Wonton Cups: Place the wonton wraps into the cups of a mini muffin pan. Spoon about 1 tablespoon of the seafood filling into each wonton wrap.
Bake the Neptune Cups: Bake at 350°F for 5 to 7 minutes, or until the wonton edges are lightly crisp and the filling is hot.
Mix the Pepper Jack Spinach Dip: Add the cream cheese, diced pimentos, diced green chiles, shredded pepper jack cheese, chopped spinach, and chopped artichoke hearts to a mixing bowl. Stir until everything is evenly combined.
Bake the Dip: Spread the dip mixture into a small baking dish. Bake at 350°F for 15 to 20 minutes, or until the dip is hot, creamy, and bubbly around the edges.
Brown the Sausage: Heat the canola oil in a skillet over medium heat. Add the smoked sausage slices and cook for 3 to 5 minutes, turning once, until both sides are browned.
Make the Pesto Mayo: Add the light mayonnaise and basil pesto to a small bowl. Stir until smooth.
Prepare the Zucchini Base: Slice the zucchini into 24 thick rounds. Spread a small spoonful of pesto mayo on top of each zucchini round.
Build the Stackers: Place one cracker-cut cheddar slice on each zucchini round. Add one fresh basil leaf and one browned sausage slice on top.
Secure and Serve: Push one toothpick through each stacker to hold it together. Serve the Neptune Cups, Pepper Jack Spinach Dip, and Sausage Zucchini Stackers as one party appetizer spread.
