I think the only way you will know if canned tomato will work is just to try. If you buy organic & unseasoned it should be fine. It would be just like buying them fresh because organic doesn't add anything yucky in there. It is just canned. If you can have canned tomato paste it is a good thickner for your chilli. You asked about tuna. I haven't had any problem with substition of canned chicken. They are mostly interchangeable. Try the tuna pasta salad (from earlier post in this thread)with chicken or even canned salmon. You could even try some cut up crab. That would be good also. (Oh I love sea food, I'm getting hungry.)
I have a recipe for Tuna Vegetable Sauce that is good....just don't use tuna. Use canned salmon or chicken.
1 TBSP vegetable oil- I used olive oil 2 cups mushrooms- I used baby bella but any would be just fine 1 stalk of celery- add as much as you like or can handle 1/3 chopped sweet red or green pepper- I left out because I don't really care for peppers 2 TBSP all-purpose flour 1 1/2 cup soy milk- You said you couldn't do soy use almond or rice milk 1 small can (6.5oz but any size around that would work) of water packed tuna- use chicken or salmon 1 TBSP ketchup 1 tsp worcestershire sauce 1/2 tsp salt
1-In large sauce pan heat oil and cook mushroom, celery and peppers covered 8-10 minutes or until soft. 2-Sprinkle with flour, stir. Gradually stir in milk. Cook over medium heat until thickened. 3-Stir in canned meat, ketchup, worcestershire sauce and salt until combined. *from the Lactose-Free Family Cookbook by Jan Main.
Serve over rice, pasta, baked potatos. You could make the carrots I posted earlier on this thread. Make some biscuts, rolls or bread. You could eat this with a salad, peas, green beans or carrots.(These veggies except the carrots are all IF.) Really just about anything. This is kind of like tuna noodle casseroll but sweeter. I really liked it. This recipe also called for onion and garlic; since you can't have them I just omited it from the recipe.
