In a medium-sized saucepan, heat the olive oil over medium heat. Add the minced garlic and sauté for about 1 minute until fragrant.

Add the chopped tomatoes to the saucepan, and cook for 10-15 minutes, stirring occasionally until the tomatoes break down and release their juices.
2 cups tomato
Stir in the lemon juice, balsamic vinegar, red pepper flakes, salt, and black pepper. Continue cooking for another 5 minutes, allowing the flavours to meld together.
1 tbsp lemon juice, 1 tbsp balsamic vinegar, 1/4 tsp red chili flakes, 1 pinch pepper, 1 pinch salt
Remove the saucepan from heat and stir in the chia seeds. Let the mixture sit for about 10 minutes to allow the chia seeds to absorb the liquid and thicken the jam.
2 tbsp chia seeds
Once the jam has thickened, taste and adjust the seasoning if needed. Let it cool to room temperature before transferring it to a jar or airtight container. Store in the refrigerator for up to one week.
