Description

This Vegan Zesty Zucchini Relish is crisp, tangy, and packed with fresh vegetables and aromatic spices. It’s a lighter homemade condiment that pairs beautifully with high-protein meals while remaining lower in carbs than many traditional relishes. Perfect for sandwiches, burgers, bowls, and meal prep.

📝 Ingredients

4 cups finely chopped zucchini (about 2 medium zucchini)
1 medium green bell pepper, finely chopped
1 medium red bell pepper, finely chopped
1 small onion, finely chopped
1 tbsp salt (for drawing out excess moisture)
1 cup apple cider vinegar
⅓ cup granulated erythritol or monk fruit sweetener
1 tsp mustard seeds
1 tsp celery seeds
½ tsp turmeric
½ tsp garlic powder
¼ tsp black pepper
¼ tsp crushed red pepper flakes (optional for extra heat)

Directions

Prepare the vegetables (10 minutes). Finely chop the zucchini, bell peppers, and onion into evenly sized pieces.
Salt the vegetables (30 minutes). Toss them with salt in a large bowl and let them sit to release excess moisture.
Drain thoroughly (5 minutes). Transfer to a colander, rinse lightly if desired, and gently squeeze out excess liquid.
Prepare the brine (Medium heat, 5 minutes). Combine apple cider vinegar, sweetener, mustard seeds, celery seeds, turmeric, garlic powder, black pepper, and optional red pepper flakes in a saucepan. Stir until the sweetener dissolves.
Cook the relish (Medium-low heat, 10–12 minutes). Add the drained vegetables and simmer gently until slightly tender but still crisp.
Cool completely. The vegetables should remain colorful with a lightly crisp texture.
Transfer to jars. Spoon into clean glass jars and refrigerate for at least 12 hours before serving for the best flavor.

High-protein cooking tip: Use this relish as a flavorful topping for grilled tofu, tempeh, seitan, or bean burgers to add freshness without significantly increasing carbohydrates.
