1 part canned tuna
1 part cottage cheese
1 multigrain bun (or bread)
Grated cheddar cheese (optional)

 

Directions:
Prepare tuna and cottage cheese mix. Spread over pieces of bread (nice multigrain buns cut in half work well for this). Top with sprinkling of grated cheddar cheese (old cheddar gives you the most flavour bang for your buck, and ensures you don't need a lot). Microwave for a minute or so, or grill under broiler (watch it—these burn fast!), till cheese on top is melted.
