Preheat the oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a mixing bowl, combine 1 teaspoon olive oil, 1 tablespoon melted vegan butter spread, and 1/2 teaspoon honey or agave nectar; stir until blended.
Add 1 cup gluten-free flour blend and 1/2 teaspoon sea salt to the wet mixture and stir to combine.
Add 1/4 cup water and mix until a dough forms; if the dough is too dry, add additional water 1 tablespoon at a time until it holds together but is not sticky.
Place the dough between two sheets of parchment paper and roll out evenly to about 1/8-inch thickness.
Peel off the top parchment, transfer the bottom parchment with the dough to the prepared baking sheet, and score the dough into 1½-inch squares with a sharp knife without separating them.
Lightly dampen the dough surface with water and smooth with your fingers, then sprinkle with extra sea salt or seasoned salt to taste.
Bake for 15–20 minutes, rotating the baking sheet halfway through, until the crackers are crisp and lightly golden; watch closely to avoid overbaking.
Let the crackers cool completely on the baking sheet, then break apart along the scored lines and serve.
