Chickpea and sweet corn bolognese; gluten-free, vegan

I have a very strict budget currently.  Not only do I have to make every meal at home but I'm also forced to resorting to cheaper recipes.  This was a excellent solution to both while remaining allergen friendly.  It is high in protein and high in nutritional content.  It's simple, tasty and very filling.

Ingredients:

Tinned tomatoes; 400g
Onion; 1, small, diced
Garlic cloves; 5, peeled and diced
Tarragon; 1 teaspoon
Sage; 1 teaspoon
Sweet-corn; 330g; drained
Mushrooms; 3 medium sized, diced
Tinned Chickpeas; 400g, rinsed and drained
Gluten free pasta; Cooked

Directions:

On medium heat, gently cook the onion.  Add the tinned tomatoes, juice and all. Add the herbs, garlic, sweet-corn, chickpeas, mushrooms. Simmer over low heat for 20 minutes.  Stir through warm, cooked pasta and serve.
