Sweet and Sour-ish Chicken

It was tasty and kept well; it was not very sweet or sour.
For 3:
3 Chicken Breasts
4 Small Onions
3 Peppers
1 Garlic Clove
2 Tablespoon Tomato Puree
4 Tablespoons Apple Juice (or Apple and Blackcurrant Squash)
2 Tablespoons Almond Flour
1 Lemon, Juice of
4 Tablespoons Vinegar
Wok

1. Peel and chop the onions. Chop the peppers. Chop the chicken into bite-size pieces.
2. Crush or finely slice the garlic.
3. Mix the garlic, tomato puree, apple juice, lemon juice, vinegar and almond flour (with a fork in a mug, if you're me).
4. Throw the onions and peppers into the pan, followed by the chicken then the sauce. Stir-fry the lot.

Volumise: Add some spinach, pak choi, lettuce and/or bean sprouts.
Add carbs: Mix some sugar into the sauce (this was in the original recipe). Add more peppers.
Add fat: Add more almond flour to the sauce. Add more oil to the stir-fry.
Add protein: Add more chicken. I have not tried this, but add some egg to the sauce. This should also help to thicken the sauce.
