Preheat oven to 425°F (220°C) and line a baking sheet.
In a large bowl, lightly beat the egg with a fork. Stir in the garlic, spices, salt and pepper. Stir in green onions, zucchini and cilantro.
Add ground turkey and mix by hand until meat binds with all other ingredients. All this can be done ahead of time and cooked when needed, just cover with plastic wrap and transfer to the fridge.
Portion slider mix into equal-sized balls, about 2 Tbsp(30 mL) each, and place on another plate or baking sheet. Flatten each slightly to form mini patties.
Preheat a large cast-iron or sauté pan over medium-high heat. Add in 1 Tbsp (15 mL) oil and sear sliders on both sides, about 3 minutes per side. Do not over-crowd pan; this can be done in batches, adding more oil as needed. Transfer to a lined baking sheet and place in the oven for 5 minutes, or until the internal temperature reaches 165°F (74°C).
Serve warm or cold, with buns and condiments of choice.
