Pesto Tuna Pasta Mug

• 75g quick-cook pasta
• 1 tin tuna
• 1 tbsp pesto
• Handful spinach
• Lemon juice
• Black pepper

1. 1

   Cook the quick-cook pasta in a mug or small saucepan of well-salted boiling water per packet instructions — usually 4–6 min. Drain, reserving 2 tbsp cooking water.

2. 2

   Drain the tuna thoroughly.

3. 3

   Return the drained pasta to the mug. Add the tuna, pesto, and reserved cooking water. Stir to combine — the water helps the pesto coat everything.

4. 4

   Add the spinach and stir — it'll wilt in the residual heat within 1 min.

5. 5

   Squeeze over lemon juice, add a grind of black pepper, and serve.
