Ingredient substitute for sriracha hot sauce Asian Glazed Chicken Drumsticks

I would like to try making this recipe. But I don't like anything super spicy. What could I use instead of the sriracha hot sauce and get a similar flavor with out the extra heat?

Ingredients

8 medium chicken drumsticks
1 cup water
1 tablespoon Sriracha hot sauce
1/3 cup balsamic vinegar
1/3 cup reduced-sodium soy sauce
2 teaspoons honey
3 cloves garlic, crushed
1 teaspoon fresh, grated ginger
the ingredient is only (mostly) for flavoring, just reduce the quantity; the recipe will still work and be less spicy.

If not wanting to be spicy at all, you could use a regular red bell pepper paste (blend/puree some red bell pepper with a little bit of olive oil (or no oil)), or maybe use a tablespoon of tomato paste.
