Step 1In a small food processor, grind together the sunflower seeds, pepitas, garlic, red pepper flakes, cumin, salt and orange zest until the nuts are finely ground. Stir in the olive oil and cilantro.
Step 2Spoon the goat cheese into a pastry bag fitted with a large serrated tube and a star-shaped tip, if you desire. Pipe about 1 teaspoon of cheese onto each of 24 mini toasts. Set aside any leftover toasts for another use. Spoon about 1/4 teaspoon of the nut mixture over the cheese. You'll have some nut mixture left over; use it to sprinkle over salads.
Step 3For the optional garnish, cut the pepper into quarters and remove the stems and seeds. Use small hors d'oeuvre cutters to cut circles, stars and moons from the pepper. Top each toast with a pepper decoration. Top the circles with a 1/2-inch piece of a cilantro stem.
