It's almost August and guess what? August is National Sandwich Month! So celebrate the sandwich by enjoying a few. They're delicious and nutritious ... well, mostly anyway. Here are some tips for building a healthy sandwich:

• Use only 100% whole grain bread. If you're cutting carbs, halve them by having an open-faced sandwich. And toasted is better.
  
• Cheese can be your friend if you don't use too much. Choose a flavourful variety like goat cheese
• Mustard is perhaps the perfect sandwich spread -- it's low-cal and low-fat. Avocado makes another good spread. Avoid the mayo.
• If tuna salad sandwiches are your thing, skip the mayo and instead mix your ingredients together with some olive oil and lemon juice, or a bit low-fat cream cheese. Yummy!
• Stay away from that high-fat bacon meatball sub--go for lean protein like turkey breast or, if you're treating yourself, smoked salmon.
  
• Load your sandwich with healthy veggies.
• If you're bringing your sandwich to work, bring the ingredients and put it all together there to avoid the soggy-sandwich situation.

My favourite sandwich is a grilled cheese, but that's a rare treat for me. What's your sandwich?
