Preheat the oven to 400 degrees F.
Heat a large saute pan over medium-high heat. Pour in vegetable broth and all vegetables and spices and saute for about 15 minutes until vegetables are tender and fragrant.
Add vegetables and all remaining ingredients to a food processor and pulse for about 30 seconds until mixture is sticky and holds together.
Line a baking sheet with parchment paper and lightly spray with cooking oil. Use a ⅓ measuring cup to divide mixture and form into balls. Place on baking sheet about an inch apart and flatten to about ½ inch thick.
Bake for about 30 minutes until surface is browned. Serve on a slider bun with baby lettuce, pineapple salsa, and coconut lime aioli.
