Directions

1. Preheat broiler to high.
2. To prepare relish, arrange bell peppers, skin side up, on a foil-lined baking sheet. Broil 10 minutes or until charred. Remove pan from oven; wrap peppers in foil. Let stand 10 minutes. Peel and finely chop. Combine peppers, parsley, vinegar, 1/8 teaspoon salt, and ground red pepper.
3. To prepare cakes, heat a large saucepan over medium-high heat. Add oil to pan; swirl to coat. Add onion; cook 4 minutes or just until tender, stirring frequently. Add quinoa; cook 4 minutes or until toasted and lightly browned, stirring occasionally. Add garlic; cook 30 seconds. Add broth; bring to a boil. Cover and simmer 17 minutes or until liquid is fully absorbed. Stir in chopped spinach. Spread hot quinoa mixture in a single layer on a baking sheet; cool 10 minutes.
